DNA Chip - Genetic Testing of the Future Essay - 2397 Words

DNA Chip - Genetic Testing of the Future Many, if not most diseases, have their roots in our genes. Genes, through the proteins they encode, determine how efficiently we process foods, how effectively we detoxify poisons, and how vigorously we respond to infections. In the past 20 years, amazing new techniques have allowed scientists to learn a great deal about how genes work and how they are linked to disease. This rapid pace of discovery of genetic factors, responsible for certain diseases, has allowed scientists to genetically test asymptomatic individuals and predict their risk of certain diseases. In this paper, I am going to discuss the following areas pertaining to the topic of genetic testing: The definition and purpose of†¦show more content†¦The information from genetic tests can help provide people and families with answers to their questions: why did this happen to my child or why do I have to suffer from this disease? Genetic tests also provide scientists with information regarding disease pathogenesis. For instance, by studying the genetic makeup of individuals with breast cancer, scientists can find out what particular mutation in the DNA, or in several genes, is causing the cancer and use that to screen high-risk individuals. Researchers are also taking advantage of genetic tests to find gene mutations that make bacteria or viruses resistant to drugs. Screening Techniques The immediate challenge in genetic testing is being able to design an effective mutation analysis method that offers a rapid, accurate, cost-effective, and user-friendly test for scanning several susceptibility genes at once. According to the article in Nature Biotechnology, by Charis Eng and Jan Viig, genetic testing techniques are grouped into two main categories: screening and scanning. Screening methods involve probing specific genes for previously identified mutations. These methods, however, are unrealistic for such diseases which are characterized by a large number of disease-causing mutations that can be virtually anywhere in the genes coding region or regulatory region (3). For example, in breast cancer, mutations can be found anywhere within the largeShow MoreRelatedA Research Study On Animal Research961 Words   |  4 PagesErasistratus, performed experiments on living animals. Likewise, Galen, a Greek physician†¦ conducted animal experiments to advance the understan ding of anatomy, physiology, pathology, and pharmacology† (Hajar 42). Debates on the principles of animal testing have persisted since the late 1860s when the â€Å"first Humane Society in the United States was established in 1866† (JA). It was during this time that various animal rights and advocacy groups began to form and the controversy over animal research becameRead MoreA Short Note On Pre Implantation Genetic Diagnosis1304 Words   |  6 PagesPRE-IMPLANTATION GENETIC DIAGNOSIS Cystic Fibrosis: Pre-implantation Genetic Diagnosis (or PGD as it is more commonly called) is majorly used to test for 2 things; specifically known genetic conditions, and chromosomal abnormality. Ultimately it allows only normal cells, which are cells unaffected by the disorder it is testing for, to be selected and used for the IVF process. PGD is popularly used as it maximizes the chance of having a healthy baby which is a big health concern of potential future parentsRead MoreThe Human Genome Project2707 Words   |  11 PagesFebruary 8, 2013 THE Human Genome Project Today I will be defining the Human Genome project. This is a project to study, research, implement, and produce a DNA sequence of the Human Genome System. The human genome project is working to try and find a way to see what every gene in the human body actually does. They have already done a DNA sequence of human genes. They discovered the human body has more proteins than they first thought; now they have to see what each protein does. When they discoverRead More The Genetic Screening Dilemma Essays1506 Words   |  7 PagesThe Genetic Screening Dilemma The National Academy of Science defines genetic screening as the systematic search of a population for persons with latent, early, or asymptomatic disease. The term genetic testing is often used interchangeably, but differs in that it only targets those individuals believed to be at high risk for an inherited condition. Genetic screening has a much broader target population. As genetic screening becomes easier, faster, and less expensive, there is a growing debateRead MoreHuman Tissue Toxicity Experimentation Will Allow For Eradication Of Animal Testing1480 Words   |  6 PagesChimpanzees are the closest living genetic animal to humans, even closer linked than gorillas. Scientist Joe Aguirre’s data conveys there’s a 1.2% difference between humans and chimpanzees DNA. Chimpanzees watch over their families and have long lasting friendships. They spend all day with their family playing, exploring the rainforest, grooming each other.According to one of PETA’s co -founders Alex Pacheco , there’s a different description of how chimpanzees spend their days in Silver SpringRead MoreBenefits of Immunotherapy from Advances in Immunology and Recombinant Dna Technology3196 Words   |  13 PagesBenefits of Immunotherapy from advances in immunology and recombinant DNA technology. Immunotherapy is a form of medical treatment intended to stimulate or restore the ability of the immune system to fight infection and disease. This can be by inducing, enhancing, or suppressing an immune response. Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while those that reduce or suppress immune response are suppression immunotherapies. ActiveRead MoreThe Development Of Super Soldiers2134 Words   |  9 Pagesthough? Will the human race ever fully develop either the genetic engineering to produce a Captain America or the exoskeleton that enhances human abilities from Iron Man? Scientific development alone won’t determine human’s abilities to produce super humans, but the ethical threshold held that humans hold will also play a huge role in determining how far the development of super soldiers will proceed. Envision a world in the future. A world where soldiers have the ability to run faster andRead MoreHuman Genome Essay1634 Words   |  7 PagesAs molecular genetic data became available, studies used them to understand human behaviors. Below I briefly summarize the structure of human genome and introduce the genome-wide association studies (GWAS). In humans, 23 pairs of chromosome constitutes the human genome. For each chromosome, the nucleotides on the opposite strands connected together to form tens of thousands of base pairs. Normally, the bonds are either adenine-thymine (A-T) or guanine-cytosine (C-G). These construct the double helixRead MoreBenefits Of Genetically Modified Animals1840 Words   |  8 PagesIntroduction It may indeed be true to say that in modern society there is a dispute about genetic modification of animals and its use. There are different opinions about this topic, and one is that these animals should be a part of our life because of some benefits for the human. Some people state that genetically modified animals cause more harmful consequences than benefits. The following research will provide the information about genetically modified animals, its advantages, and disadvantagesRead More Are Genetically Modified Foods the Way to Go?

No one has seen a gene, and the best teaching by the brightest minds cannot adequately convey the ideas of the uniqueness of the genome and how we can read this uniqueness. In short, very few people understand the science behind genetic manipulation, and this is th e reason for the irrational fear. The manipulation of genetically modified and
