Charles Darwins Theory of Evolution Essay -- Natural Selection, Evolu
Introduction It is commonly thought today that the theory of evolution originated from Charles Darwin in the nineteenth century. However, the idea that species mutate over time has been around for a long time in one form or another. Therefore, by Darwinââ¬â¢s time the idea that species change from one type into another was by no means new, but was rejected by most because the proponents of evolution could not come up with a satisfactory mechanism that would explain this change. But how did Darwin come up with an acceptable theory of evolution, and how did Darwinââ¬â¢s proposal of natural selection impact the theory of evolution? The answer lies in the study of the works of others, and in the works of Darwin himself, through his theories, his travels and his scientific pioneering. The most influential evolutionary theories prior to Darwin were those of Lamarck and Geoffrey St. Hilaire, developed between 1794 and 1830. Lamarck suggested that species evolve through the use or disuse of particular organs. In the classic example a giraffe that stretches its neck slightly to reach higher leaves will gain in neck length, and this small gain would be passed on to its offspring. (Poirier, McKee, 1999) St. Hilaire, on the other hand suggested that the change was discontinuous, large in magnitude, and occurred at the production of offspring. However, these theories of evolution were based on explanations that offered no demonstrated mechanism. (Bowler, 1990) Darwinââ¬â¢s theory of evolution differs in that it is based on three easily verified observations. First, individuals within a species vary from one another in morphology, physiology, and behavior. Second, variation is in some part heritable so that variant forms have offspring that ... ....

Anything Goes Play Review Essay
On Thursday, February 20th, I finally saw my first college play. Unlike the majority of plays Iââ¬â¢ve seen in the past, Anything Goes actually caught my attention for once. Musicals and plays were big in my high school, but East Central took it to the next level in terms of talent and preparation. After watching the play, I came to the conclusion that Mrs. Grace Austin did a wonderful job as the director, putting on an intriguing show. Iââ¬â¢m no expert in terms of set design, but I was really impressed with how real it looked. While watching the play, I could easily imagine myself being on that ship. What made it look most lifelike was the lifesavers hanging up alongside the walls of the shipââ¬â¢s staircases, and the authentic looking wood making up parts of the ship. Opposite of the set design, I thought that the lighting could actually have been a little better. While there was nothing actually wrong with the lights, I think there was room for improvement. The lights were very simple throughout most of the play, which is sometimes good, but there could have been more color and movements with the lights to make it more exciting. The spotlight, however, was perfect. As for special effects, there was nothing noticeable besides the lights. Good thing that the play had decent lighting, that way the audience was able to see the perfectly fitting costumes. Everyone was mostly dressed up and looking nice to match the luxury theme. I liked everything about the costumes, but I didnââ¬â¢t get why the angel costume was red. It would have made more sense to be in white, but did not make much of a difference. All of these things came into play to make a pretty good performance. The main characters were Riley Dunn who played Billy, Sam Rodgers who played Hope, Lee Garner who played Evelyn, and Sarah Hopp who played Reno. Overall, Anything Goes turned out to be a pretty good story line. And thanks to the ECC casting crew and Mrs. Grace Austin, they provided a high quality production that I wouldnââ¬â¢t mind seeing again. Even being critical, I would give ECCââ¬â¢s production of Anything Goes a 7 out of 10. It was enjoyable to watch.

One Act Play
There is a card table, folding chairs, newspapers, trade magazines. TERESA is sitting on a folding chair at the desk , talking to JAKE, who is consulting THE JOB FINDER'S GUIDE and taking notes in a notebook from his briefcase. DEBBIE enters, looks around. TERESA I wear an extra sweater and a hat. That's what my mother did when she was a girl, during the Depression. The kitchen stove was their heat. (notices DEBBIE) Can we be of help, dear? DEBBIE Group's supposed to be at 10:30, isn't it? TERESA Yes, butââ¬â DEBBIE I'll wait. ( DEBBIE sits, takes out newspaper, begins reading. ) TERESA (to JAKE) How is Janet doing?JAKE Better. Takes her a couple weeks to bounce back from chemotherapy. But she's up and around, now. Cleaning out the kitchen drawers. TERESA And your boy? JAKE I told Park School I was going to have to pull Jason out of there. (sits) They came up with a scholarship. TERESA (pats JAKE's shoulder) Well, now. That's good news. JAKE Is it? Jason's grades are dropping. He 's out too late, comes back with bullshit ââ¬âsorry. You'd think that being out of work I'd have time to ride herd on him, but with hustling a job and taking care of Janetââ¬â. TERESA A boy that age can be a real pill. Especially at a time of crisis.JAKE You're telling me this is normal? TERESA I saw it my boys. There's stress, and a boy feels he ought to be pitching in to help. But there isn't much he can do, really, is there? JAKE He can at least not add to our worries! TERESA That's true, but at his ageââ¬â . Probably the guilt is driving him wild. JAKE School's Jason's job. Seems to me it's that simple. DEBBIE Maybe your kid's just not the kind who can block out the real world. JAKE (rises, turns to DEBBIE) Seems to me a person can at least try! (pause. DEBBIE hides behind newspaper) TERESA ( brings JAKE back) It was a real shame about that position in Nashua.JAKE Yeah. I thought they'dââ¬â. Butââ¬â. You know ââ¬âI could never mention this to Janet, it'd kill herââ¬â but I wonder. Can a personnel office find out about cancer? Go though medical files? TERESA Doctors' records are confidential. DEBBIE (lowers paper) Ha! Sure. And Santa Claus lives at the North Pole. (pause) Sorry. S'none of my business. JAKE Maybe it's my age. I'm fit, but ââ¬â do you think I should get a hairpiece? DEBBIE (laughs, loud. JAKE and TERESA look at her. She holds up the comic page) Dilbert. (they turn back) MERRIK (enters ) Good morning. JAKE (goes to Merrik) Hey, look, it's Merrik back!How's it going, big guy? MERRIK (shaking hands) Good. It's going good, praise the Lord. JAKE I thought you had a job. MERRIK I did. I mean, I do. Just taking longer than we figured. JAKE Georgia, wasn't it? MERRIK Right. Georgia for training, and then traveling between the territories. TERESA But your wife's careerââ¬â. MERRIK Secretarial stuff. A woman can do that anywhere. DEBBIE Anywhere there's a job. MERRIK There's secretarial in Georgia. Alice says, ââ¬Å "At $5. 15 an hour? â⬠But money goes farther down there. No oil bills, housing's less than half. â⬠¦ JAKE I'd say, sell while you can!This market is so overpricedââ¬â MERRIK Alice says the company will fold: a job that can be done cheap in Georgia will be done even cheaper in Pakistan or Prague. JAKE Well, if you do put your house on the market, give me first shot at the listing, will you? (KIM enters, stands silently) MERRIK You're still part time at real estate? JAKE Me and everybody else who's run out their unemployment. KIM Is this Bright Horizons? DEBBIE That's what they call it. KIM I had trouble findingââ¬â TERESA Don't worry, you're not late. DEBBIE You are, but the Counselor's later. MERRIK What's going on? crosses to phone) When I called, the overnight message was still on the answering machine. (fusses w/ machine) TERESA Oh, dear. KIM What does that mean? TERESA People have had to give up their phones, sometimes, or they may even be homeless. Being able to use this answering service makes themââ¬â JAKE Seem normal. TERESA Employable. Able to return calls. MERRIK ââ¬Å"Executive Officesâ⬠, it says. After ten, and nobody's here? ( DEBBIE laughs) TERESA Can we reset it? JAKE How hard can it be? Half the unemployed people here used to be in high tech. TERESA If you can't change the message, at least turn it off.DEBBIE (unplugs machine) Off with the bullshit! (to MERRIK) Your Georgia job ââ¬â Did you get it through this office? MERRIK Not really- DEBBIE (goes back to her chair and paper) Now, how did I guess that? KIM How did you get it? MERRIK I heard about it from my cousin, a friend of hisââ¬â DEBBIE My Dad ââ¬Ë s cousin got him work in construction, once. In Jersey. He'd only get home about every third weekend. Meant he and Mom never had time to work things out. All they did was fight. TERESA That sounds so like my mother's stories of the Depression. When my grandfather went looking for odd jobs, weeks at a time â⬠¦..MERRIK The job's like auditing, but there's a sales aspect, too. First our team has to convince the company that we can save them money. JAKE Sales ability! Now, that doesn't surprise me, Merrik. I can see that in you. MERRIK You think so? I can do it, I have theââ¬â . JAKE 90% of any job is sales. KIM Is that really true? I'm terrible. Couldn't even sell girl scout cookies. JAKE Got to market your personality as well as your skills. MERRIK As soon as interest rates rise, real estate will be in the toiletââ¬â JAKE Depends on what market. I mean, it's not the class of people who can afford a couple million bucks who are hurting, is it?But those sales take time, those people are chooseyââ¬â MERRIK The Georgia job, I don't get paid until the adjustments come in. It can take 6 months, 9 monthsââ¬â I tell my wife, have faithââ¬â TERESA If you can be sureââ¬â MERRIK My kids are all the time after me, they want stay here where their friends are, but I tell them have faith. The church down there's strong, s'got real spirit. They'd make new friendsââ¬â KIM My brother was sent South for basic training. He said the people treated him like dirt. DEBBIE (reading, exclaims aloud) Jesus Christ! MERRIK Young lady! DEBBIE Sorry. I didn't mean ââ¬â this story, did you see it?Unemployed postal worker in St. Louis, shot up his boss and three carriers and a cop. At his house, he'd already killed his wife and kids. MERRIK Let me see. (takes newspaper) TERESA I heard about that. On the radio. JAKE There were a rash of these things 10, 12 years ago. DEBBIE During the last round of lay offs. MERRIK The Post Office must be hiring straight out of the loony bin. TERESA Veterans get extra points on the exam, so there may be a lot who are trained in firearms. MERRIK Combat flash back, you think? JAKE Post traumatic. DEBBIE Postal traumatic. MERRIK Well, they'd better weed out the crazies, and fast.DEBBIE Oh, the crazies are being weeded out. Along w ith the alcoholic, lazy, and the ones who can't put in enough overtime. MERRIK About time! DEBBIE Good thing they didn't start weeding till my uncle Adam took the pension. He'd have been mad crazy enough to get down his shotgun. course, he drank, some, and he was certainly slow. But neither rain nor snowââ¬â MERRIK Four days, for a letter from my wife! If the mail went privateââ¬â DEBBIE There'd be no mail on Saturday, carriers would be green carders getting $5. 15 an hourââ¬â KIM And no veteran's preference points? MERRIK What's your point?KIM My brother enlisted to get training for a good job. TERESA ââ¬Å"Be all you can beâ⬠? KIM I've thought about enlisting too. But Buddy lost the fingers off his right hand: what's he going to do when he gets out? He can't go back to meat cutting. MERRIK Don't expect the VA. They're shutting down, one by one. TERESA This office could find him something, dear. Helen's a lifesaver. DEBBIE Something ââ¬Å"Executiveâ⬠? TERESA Education. Retraining. This is a really good program, at least for young people. Oldsters like me, nobody wants to hire us whatever we can do. KIM They'd better find Buddy something. Cause he's so angry, he mightââ¬âMERRIK So it's OK to shoot people? If you lose your job? DEBBIE No, it's not OK. But I understand it. Don't you? At least a story like this one makes more sense to me than the crap that's in the business section: DOW up; GE announces more layoffs; the Technology Council wants more ââ¬Å"flexibilityâ⬠in the visa program, to meet the overseas competition Do they really think all these computer whizzes who used to make a hundred thou a year are going to go quietly into burger-flipping? KIM What else can they do? DEBBIE How many Luddites does it take to unscrew all the light bulbs? JAKE God knows there's a lot of frustration.MERRIK (to KIM) God knows, that's a true saying. If we cleanse our hearts, and trust Him, He answers our prayers. JAKE I've had bosses it wo uldn't break my heart to see bleed. But shoot his own kids? MERRIK Now, that makes sense, in a certain cock-eyed way. If a father's desperate enough to kill, but he loves his kids, how could he leave those kids to face it? I'm not saying he's thinking right, butââ¬â ! TERESA I wish Helen would get here. With two new clientsââ¬â DEBBIE I'm not new. This is lay off number 5. Or maybe 25, depending on how you count it. TERESA Temp jobs? I don't think those count. KIM They'd count for me!I can't find anything at all. TERESA Substituting, temping, you know from the start it's not going to last. JAKE Nothing lasts, these days. You got to plan ahead. Train or re-train. KIM Sure, train. But for what? DEBBIE Train, they told me. So now I'm in debt up to my ears for what it cost me to learn programming. JAKE Programming used to be hot. DEBBIE And now it's not. JAKE Still. In a downturn, that's the recommendation. Retrain, add new skills to your resume. DEBBIE Keep paying tuition. Dang le that ââ¬Å"good jobâ⬠carrot, the old donkey keeps plodding along. TERESA Education is a person's best investment.DEBBIE Oh? Where's it got you, lady? You just here to write a book? TERESA I never seemed to be in the right place at the right time. If I hadn't left teaching to raise my boys, I'd be retired on a pension by now. But as a substitute, Iââ¬â DEBBIE I started out in the tool shop, with my dad. $12. 50 an hour, 18 for overtime. After the 3rd layoff I took the Expert Advice. Went to college. Got my 2 year certificate. Officially qualified to do scut work for some creep in a suit at seven fifty an hour. Seven fifty! With which I'm supposed to buy all this fashion shit and ââ¬Å"look professionalâ⬠for Chrissake!But even in drag, all I could get was temp work. So then it's back to school for Programmingâ⬠¦. KIM I can't even get part time Walmart! I thought anybody could get that. TERESA As soon as Helen gets here she'll help you. She has a comprehensive list: openings, training programs, subsidies, scholarshipsâ⬠¦.. (phone rings) JAKE Should we answer it? DEBBIE Well, they can't leave a message, we unplugged the machine. MERRIK (answers) Executive offices. KIM (to TERESA) I hope you're right. This feels like it may be my last chance. DEBBIE Everybody's last chance. JAKE You're young, you're healthy.It's not the end of the world. MERRIK Yeah. I'll tell people. (hangs up) This office is closed. TERESA Oh, my dear God. Are you sure? This office? KIM Should we go to some other one? MERRIK Nobody knows. They've all been laid off, here. Budget's gone, the governor vetoed the restoration. JAKE That was Helen? TERESA But what will we do?

The Challenging of Institutions Within the Art World
TERM 1 WEEK 5 The challenging of institutions within the art world ââ¬Å"Artworks are designed to challenge institutions and test the limits of tolerance,â⬠(John A Walker) as they challenge the historical context of traditional institutions, such as conventions, government and religious views, by viewing works. Through the post-modern frame (examining how artists and artworks challenge traditional bounds and rules, and conventions in art including concepts of originality and authenticity), artists in contemporary societies have started to use non-conventional, appropriated techniques to create new meaning within their works- shocking audiences and challenging institutional tolerance, ââ¬Ëlimits of toleranceââ¬â¢ (John A Walker) often being assessed through audiences reaction, censorship and the banning of exhibitions. The Sensation Exhibition is a collection by Charles Saatchi opened in 1997 to attempt to define a generation of artists, shocking the world with their controversial themes and medias. Three works within this exhibition that challenge the institution and tested the boundaries of their tolerance were The Holy Virgin Mary (1996) by Chris Ofili which explores the hypocrisy of Catholicism, The Physical Impossibility of Death in the Mind of Something Living (1991) by Damien Hirst which deals with the cycle of life and death and My Bed (1999) by Tracey Emin which explores the most brutal times in Eminââ¬â¢s life. Each of these works tests the boundaries of tolerance for institutional galleries, religion, society and morality, challenging and confronting the way they are viewed within each institution. The Sensation Exhibition, lead to an up roar by members of society, including aspects of the art world Chris Ofiliââ¬â¢s, The Holy Virgin Mary was a leading cause of controversy in the Sensation Exhibition due to the potent mixture of themes such as purity, pornography and excrement. On two lumps of dried, varnished elephant dung, sits Ofiliââ¬â¢s work of an African American Madonna, covered in Renaissance styled drapery. The Holy Virgin Mary appropriates and recontextulizes the traditional Virgin Mary, not only by this but, by juxtaposing the pure, innocence of cherubs and substituting not only their physicality on the canvas but also their meaning with photographs of female genitalia. Ofiliââ¬â¢s work plays with the idea that women should bear full chastity but also embarrass her sexuality within, highlighting the hypocrisy of Catholicism. The Holy Virgin Mary challenges the Catholic Church as an institution through the recontextulization of the Virgin Mary- a pure and sacred symbol in Catholicism. How individual views each work within each gallery institution is different. ââ¬Å"You donââ¬â¢t have the right to a government subsidy for desecrating someoneââ¬â¢s religion. â⬠(Rudolph Giuliani- Mayor of New York) The Holy Virgin Mary provoked the anger of Giuliani, not only outraged because of the pornographic elements of the artwork but also its painting surface and support on elephant dung. For Guliani, this work was interpreted as an insulting and blasphemous attack on the holy status of the Virgin Mary. While Giuliani sees the work as disrespect to religion, Ofili himself sees the piece as a work of beauty, the elephant dung highlighting the natural phenomenon of life, another entity of purity within itself. Through Ofiliââ¬â¢s work, religion has become a reoccurring subject of art, not because of any religious beliefs held by the artist himself, but to show the result of change in society, including religions place therein. Society has been conditioned by institutions to behave in a contemplative, reflective manner when viewing museum works. Every individual views a work differently, thus challenging the limits of not only an individualââ¬â¢s tolerance but also an institution as a whole through the general publics expression and reflection on a work. Damien Hirstââ¬â¢s The Physical Impossibility in the Mind of Something Living explores the confronting idea of death in a hypocritical light. Hirstââ¬â¢s use of the physical form of a dead shark, which is known as a symbol of death and fear is very confronting. The public viewing this work may question these stereotypical ideas associated with this animal whilst being able to stare it directly in the face, in all its silence and serenity. The use of formaldehyde to preserve the external remains of the dead shark makes the audience think about the internal happenings of not only the shark but also themselves, as an individual and what happens in your mind when you are physically dead. Damien Hirstââ¬â¢s quest to be edgy is as boring as it is callous. It does not matter whether Hirst killed the animals himself or sat by while thousands of them were massacred for his own unjustifiable amusement. Sharks are a part of nature and should be aloud to live in the wild instead of destroyed for something predictable and unimaginative. â⬠(Same Glover, PETA) The reaction of PETA (People for the Ethical Treatment of Animals) towards Hirstââ¬â¢s was that he was barbaric and cruel, not recognising Hirstââ¬â¢s works as art. Presented in a gallery space, with the subject matter and materials used, suspended within a glass tank is an unconventional art form in itself- also contributing to the tolerance and challenging of the gallery institution and the public as an institution. This reaction, ââ¬Å"In keeping with the piece's title, the shark is simultaneously life and death incarnate in a way you don't quite grasp until you see it, suspended and silent, in its tank. It gives the innately demonic urge to live a demonic, deathlike form. (New York Times 2007) This extract emphasises the effect this piece has on the audience when seen up close and personal in the actual gallery space, thus testing the limits of audience and gallery tolerance and challenging the space it exhibits in. Art within an institution is used to influence the publicââ¬â¢s attitude and beliefs or, in some cases, relate to a smaller group who have gone through the similar experiences in life. ââ¬Å"It was as if it was no longer the task to produce masterpieces, but to use the making and showing of art in the service of some more socially urgent endeavourâ⬠. Arthur Danto) Tracey Eminââ¬â¢s, My Bed does exactly this. My Bed explores an individualââ¬â¢s issue of identity, sexuality and morality in a brutally honest way through the contemplation of suicide. Eminââ¬â¢s work confronts an audience by letting you into her world to explore the toughest yet greatest times in her life. This subject is much more fragile than Hirstââ¬â¢s and Ofiliââ¬â¢s work as it makes the connection between a personal hardship in Eminââ¬â¢s life rather than the fear of death felt in Hirstââ¬â¢s work or the traditional vs. modern exploration created by Ofili. By putting something, so personal such as a bed on display in a gallery setting- the traditional design of the institution as a place for a ââ¬Ëmasterpieceââ¬â¢ has been challenged through the raw and honestly confrontation of Eminââ¬â¢s work. ââ¬Å"Emin brings life in things taken from the real world ââ¬â into the art gallery and leaves it there, more or less unchangedâ⬠(The Telegraph) This statement supports Eminââ¬â¢s connection to individuals who go through depression and contemplation of suicide through the raw, untouched entities of her bedroom, exaggerating the self-absorption and self-pity felt in an isolated room full of negative, undermining houghts. Through placing such an intimate entity in a gallery space and making it her own room, Emin challenges the gallery as an institution by making it a more personalized experience for not only the people who have gone through this hardship, but everyone by placing something so uncanny in a public gallery, bl urring the line between private and public externalisation. ââ¬Å"Artworks are designed to challenge institutions and test the limits of tolerance,â⬠by attempting to define a generation of artists and their diverse and controversial artistic visions. Through different medias, attributing to their post modernistic conventions, The Holy Virgin Mary by Chris Ofili, The Physical Impossibility of Death in the Mind of Something Living by Damien Hirst and My Bed by Tracey Emin all challenge and test the boundaries of tolerance for institutional galleries, religion, society and mortality. Each work explores the recontextulization of gallery spaces through the historical context by redefining an institution as a place that challenges history rather than upholds the traditional design of conventional, ââ¬Ëclassicalââ¬â¢ art. Institutions such as PETA, religion, governments and the public, have all been challenged by artworks, thus redefining institutions and being designed to test their limitations.

Final Project - Essay Example The reason for taking up the diversity consciousness course was to acquire more knowledge about diverse cultures. The topic diversity attracts me or influences me a lot as I belong to the East African originating from Ethiopia and reside in the United States. The cultural differences, the approach and the differences in value helped me to understand and focus on personal growth by staying in between the people of diverse culture (Azcentral, 2013). The diversity course has influenced my mindset and my behavior towards the people of different cultures. I have now started to identify and respect the people of different cultures. The course is helping me in understanding the values of the diverse culture, religion and the behavior. Moreover, the awareness regarding diversity has helped me in understanding the fact that people are different and their attitudes and ideas should be respected. The awareness assists me in appreciating the fact that individuals of different places are ââ¬Å"not like usâ⬠and hence have learnt to respect the differences instead of complaining. The diversity awareness has helped me in understanding my peers better, improve my communication and avoid the level of confusion. The prominent reason for the conflicts is differences hence the awareness regarding diversity helps in avoiding the conflicts faced, usually when we are new to the country (McLauren, 2009; The Pennsylvania State University.). The understanding of the diversity in the culture and communication has affected my thought process to a great extent. The differences of cultures have made me more tolerant and allowed me to respect the diverse cultures and their differences in opinion. The understanding of the differences has helped me in understanding the uniqueness of the person. Before identifying the importance of diversity, I thought the USA to be a

Non-profit Organization - Essay Example 2). As a collaborating health agency, the CDC was noted to be working with other partners through health care agencies and institutions with the objective of monitoring the health status of the general public; detecting and inspecting eminent health problems; conducting the needed research to promote prevention of illnesses; designing and developing policies pursuant to health care and prevention of diseases; promulgating health behaviors; enhancing public awareness regarding the promotion of a healthy and safe environment; and providing the crucial training for leadership development within the healthcare setting. The origin of the CDC could be traced on the 1st of July, 1946 when it started as the Communicable Disease Center (CDC), also located in Atlanta, Georgia through humble beginnings. The initial thrust was the prevention and control of malaria, and interesting facts from its official website indicated that during the early years, ââ¬Å"the CDCâ⬠²s early challenges included obtaining enough trucks, sprayers, and shovels necessary to wage the war on mosquitoesâ⬠(CDC: Our History par. 5). In contemporary times, CDC has been world renowed as a governmental health agency tasked with various crucial programs and projects that safeguard the health of the American population and focusing on the following key areas: supporting state and local health departments, improving global health, implementing measures to decrease leading causes of death, strengthening surveillance and epidemiology, and reforming health policies (CDC par. 12). Due to the extensive scope of CDCââ¬â¢s functions and tasks of safeguarding the health of the entire American population, there were ten great public health achievements that were revealed so far within the 21st century, as follows: (1) provision of immunizations; (2) ensuring motor-vehicle safety; (3) monitoring workplace safety; (4) controlling the spreading of infectious diseases; (5) instituting effective measures to reduce

Multiple alleles and sex chromosomes Assignment
Multiple alleles and sex chromosomes - Assignment Example A personââ¬â¢s blood type is determined genetically. It is imperative that a thorough understanding of the DNA is ascertained for better grasping of the multiple allelesââ¬â¢ direct contribution to the inheritance of ABO blood systems. Histones allow the packaging of DNA and condense it into chromatin. Histones are highly alkaline proteins with a positive charge while DNA is negatively charged (Pollard and Earnshow, 2007). Accordingly, Histones and DNA will interact with the Histones acting as spool materials in which the DNA can attach itself. Histones and the DNA will form the nucleosomes, which on further packaging and separation by linker DNAââ¬â¢s, result in chromatins. Further condensation of the chromatins and other proteins will result in the chromosomes. Chromosomes can, therefore, be defined as a carrier of genetic information as it contains highly packed DNA and Histones (Pollard and Earnshow, 2007). DNA consists of nucleotide substances that are further comprised of deoxyribose, phosphate groups and the four bases. DNA is generally a linear sequence of ACTG bases that define the physical traits in an organism. DNA can be viewed as a double helix, which when separated produces two parallel linear strands of the nucleotide letters where each strand is complimentary to each other (Pollard and Earnshow, 2007). A interlocks with T while G interlocks with C. The exact order of the four bases along the molecule represents the coded genetic information. ... Genomes are the genetic information defining each organism, which is determined by the genome sequences depending on how the four bases are aligned (Pollard and Earnshow, 2007). It is also important to note that apart from genes, a genome also contains other DNA sequences that do not encode genes. The human body has three billion pair of DNA, 28000-34000 pairs of genes and 23 pairs of chromosomes (Pollard and Earnshow, 2007). This translates into a myriad sequences which could explain the wide scope of genes. Genes are the basic and structural and functional units of genetics; therefore the basic unit of inheritance that is composed of DNA and RNA. They control the cells by directing the formation of proteins. An allele is an alternative form of a gene and it represents the different version of a similar gene (Pollard and Earnshow, 2007). A gene is comprised of two alleles and each individual carries only two alleles of each gene, which exhibit a dominant recessive relationship. The dominant allele will prevail over the recessive gene and is responsible for the resulting phenotype. Recessive alleles will, therefore, not affect the phenotype of the individual. A pair of allele resulting from the various combinations of alleles can be referred to as the genotype while the resulting physical trait as a result of the genotype is called the phenotype (Pollard and Earnshow, 2007). Multiple alleles arise where there are three or more different alleles of a particular gene in a gene pool. This results into polymorphism where two or more phenotypes exist in a given population (Pollard and Earnshow, 2007). The occurrence of multiple alleles can be attributed to difference in the non-coding DNA found between genes rather than
