What would you do if you were given up the power to change your genetic code from brown hair to platinum-blonde?. Man has had this ability through natural selection for some season without knowing it, plainly in the near future scientist will be able to speed the process of natural selection by ever-changing a persons genes. Scientists have identified what constitutes human deoxyribonucleic acid located in the nucleus of a cell. The homo Genome Project was established to identify the genes that score us who we are and is now an international organization. The massive task of identifying the legion(predicate) gene combinations has created a problem. In the nucleus are 22 genomes, incontrovertible devil sex chromosomes which have already been identified. In the 22 genomes 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 s tarted in 1990 and whose job it is to identify the letters or chromosomes in DNA. These letters gift nucleotides called adenine, guanine, thymine, and cytosine (or A, C, T, G). (92 BSCS pg. 1) The Human Genome Project idea originated in the mid 1980s and was discussed in the scientific community and media through the latter part of that decade. In the get together 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 Research) 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 fastly. A major shoot for is to determine how evolution proceeds from lower organisms to humans, and discover why the little genomes of animals have less junk or unneeded DNA. Geneticists use two types of maps to characterize the genes they discover--a genetic linkage map and a physical map. A genetic map registers the duration between the fragments of DNA we know concord 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 easily as generate new mapping techniques. (Instrumentation) Scientists can map genes but it is still expensive.
