The Human Genome Project Essays - Genomics, Genetics, Free Essays The Human Genome Project title = The Human Genome Project The Human Genome Project, What Is It? What would you do if you were given the power to change your genetic code from brown hair to blond?. Man has had this ability through natural selection for some time without knowing it, but in the near future scientist will be able to speed the process of natural selection by changing a persons genes. Scientists have identified what constitutes human DNA located in the nucleus of a cell. The Human Genome Project was established to identify the genes that make us who we are and is now an international organization. The massive task of identifying the numerous gene combinations has created a problem. In the nucleus are 22 genomes, plus two sex chromosomes which have already been identified. In the 22 genome there are approximately 3 billion base pairs of DNA which contain 50,000 to 100,000 genes, a basic unit of heredity. The identification of these base pairs is the goal of the Human Genome Project, which started in 1990 and whose job it is to identify the letters or chromosomes in DNA. These letter s represent nulcleotides called adenine, guanine, thyamine, and cytosine (or A, C, T, G). ('92 BSCS pg. 1) The Human Genome Project idea originated in the mid 1980's and was discussed in the scientific community and media through the latter part of that decade. In the United States the combined effort of the Department of Energy and the National Institute of Health were involved in the project planning. (The National Center For Genetic Reasearch) The Human Genome Project has several goals including identifying the genes of a human assessing the genes and comparing human DNA to that of bacteria, yeasts, the fruit fly, mice, and the Arabidopis thaliana, a small genome plant that grows rapidly. A major purpose is to determine how evolution proceeds from lower organisms to humans, and discover why the smaller genomes of animals have less junk or unneeded DNA. Geneticists use two types of maps to characterize the genes they discovera genetic linkage map and a physical map. A genetic map registers the distance between the fragments of DNA we know according to the frequency with which they are inherited. The physical map measures the actual physical distance between two markers. Scientists want to map and develop technology for rapid genotyping, plus develop markers that are easy to use as well as generate new mapping techniques. (Instrumentation) Scientists can map genes but it is still expensive. One of the ongoing goals of the Human Genome Project is to get the cost of mapping a gene down to 50 cents per base pair. ('92 HSCS pg.3) The enormous information that is and has been generated by the project is used to link sites together around the world through the internet and now some information can be acessed by the general public. Another of the project goals is to create a sequencing capacity at a collective rate of 50 Mb per year. This is supposed to result in the completion of 80 Mb by the end of FY 1998. Many people question whether the Human Genome Project is worth the money spent on it and will it be used negatively toward those who have traits that are considered undesirable by insurance companies and other corporations? The HUMAN GENOME ORGANIZATION has a council of scientists and doctors worldwide who meet to discuss the effects of identifying an individual's genes. In the 1996 Genetics Confidentiality and Nondiscrimmination Act an attempt to addresss this issue as noted in Section 2, " The DNA molecule contain's an individual's genetic information that is uniquely private and inseparate from one's identity. Genetic information is being rapidly sequenced and understood. Genetic information carries special significance. It provides information about one's family, and more importantly, provides information about one's self and and one's self perception." Genetic information has been misused, harming individuals through stigmitization and discrimination. The potential for misuse is tremendous as genetics transcends medicine and has the potential to penetrate many aspects of life including health and life insurance, finance, and education. Experts advocate that genetic information should not be collected, stored, analyzed, nor disclosed without the individual's authorization. Current legal protections for genetic information is, however, inadequate. Uniform rules for collection, storage, and use of DNA samples are needed to protect individual privacy and prevent discrimination while permitting legitimate medical reasearch. The report further states that the reading of a minors DNA should be only with parental or legal guardian consent and only

10 Tips to Improve Your Writing Skills

10 Tips to Improve Your Writing Skills 10 Tips to Improve Your Writing Skills 10 Tips to Improve Your Writing Skills By Mark Nichol 1. Prepare Absorb information about writing, but don’t overwhelm yourself. I’ve been known to read a writing handbook or editing manual cover to cover, but I recommend reading one chapter or section at a time and absorbing information from online resources in similarly small doses as well. Our website is a good starting point, as it features thousands of posts about specific grammar, syntax, and style topics as well as vocabulary-building posts and more comprehensive posts about writing, editing, and language. 2. Practice Work on your writing every day. Commit to a daily writing exercise, even if you have only five minutes to spare. If you write for a living, or writing constitutes a significant proportion of your daily tasks at work, still set aside time to practice other forms of composition. Style or subject matter can vary day to day, or you can decide to, for example, respond in writing to something you experienced with any of your five senses (including anything you watched or read by way of a form of media). Alternatively, find a list of writing prompts online, and use the next one on the list each day, or choose one randomly. (Encourage family members or friends- or even coworkers- to join you in producing their own responses.) 3. Engage with Others Participating in a group learning activity is a great motivator. When you have paid for a class and/or scheduled time for attend classes or workshop sessions, you’re more likely to persevere, and completing assignments and projects will help you establish and/or maintain your writing discipline. If you’re intimidated by a group setting, consider finding a writing partner with whom you can exchange drafts and/or discuss concepts and practice skills, then graduate, on your own or with your partner, to a course or workshop. Alternatively, seek out online courses or groups. 4. Read Read for education, enjoyment, and enlightenment. For the most part, with recreational reading, just sit back and enjoy yourself. But consider devoting occasional sessions to analytical reading, in which you highlight particularly effective words, phrases, sentences, and paragraphs and think about why they stand out, and apply the techniques to your own writing. 5. Organize Use organizational techniques such as outlines and diagrams. Brainstorm keywords and essential ideas or plot points. If other forms of creative expression stimulate you, use them: Listen to (or play) music to inspire a certain mood, collect photographs or illustrations of people, places, and things that suggest elements you want to incorporate into an essay or a short story, or draw sketches of characters or settings to help you visualize them. 6. Research and Fact-Check Whether you’re writing nonfiction or fiction, take care to write authoritatively. If you’re writing a short story or a novel, read about the historical background of the setting to make sure that you are not introducing counterfactual or anachronistic elements. When crafting a newspaper, magazine, or website article, or a blog post, educate yourself on your topic, and double-check quantitative information: proper names; affiliations and relationships; and dates, distances, dollar amounts, and so on. 7. Be Flexible Write with an open mind. Be flexible about changing the focus of an article or essay or the protagonist or plot of a short story or a novel. Question your assumptions, and accept that your initial goal or message may not be the most effective or useful one, or the one that you are prepared to express just now. 8. Draft Expect to be dissatisfied by your first draft, and don’t assume that your second draft is your last. Whether you’re writing a blog post or a book manuscript, the initial iteration may only slightly resemble the final draft- which, if you also submit it for editing, will differ from the edited version. Some writers have managed to produce an admirable piece of writing on the first try, but you will very likely spend as much time revising your first draft (and subsequent efforts) as you did producing it, if not more time. Embrace the opportunity to improve your baseline output by reorganizing, inserting, and omitting text; reshaping phrases and sentences; and replacing bland verbs and tired clichà ©s and vague descriptions. 9. Hire an Editor You’re free to post to your own blog or self-publish your novel without any further mediation, but you will be more successful as a writer if you accept that objective assistance enhances virtually everyone’s prose. Hiring an editor is a significant investment of time and money- editorial attention to a long novel, for example, can cost a couple thousand dollars and take several weeks- but if you find a good editor, the investment will be worth it. (And note that with any other service, you often get what you pay for, so when choosing an editor, focus on quality of results you will obtain rather than quantity of expense you will incur.) If you can’t afford such an expense, at least ask a friend or acquaintance to go over your writing for you, and perhaps offer to edit something of theirs in exchange or to provide a service of similar monetary value (dog walking or pet sitting, clerical or organizational assistance, repair or construction, and so on) in return. Just understand that assistance from someone on the basis of acquaintance is less likely to be either objective or of professional caliber. Choose an editor who knows what they are doing and will not hesitate to provide revisions and critiques at the risk of damaging your ego. 10. Practice Humility Perhaps you were praised at home and/or at school for your writing, or you have won one or more writing awards, or you have had articles or stories (or even books) published. Any or all of those achievements constitute a good start. But you are still developing as a writer, and you always will be. Continue to practice these habits and welcome other opportunities to grow functionally and creatively as a writer. Want to improve your English in five minutes a day?
