Deciphering the Code of Life The Human Genome Project
Deciphering the Code of Life - The Human Genome ProjectThe study of all genus of various organisms will yield answers to some of the most intriguing questions about life: how organisms evolved, whether synthetic life will ever be possible and how to treat a wide range of medical disorders. Human genome contains all of the biochemical instructions - in the form of the DNA bases A, T, C and G- for making and containing a human being. The payoff from the reference work will come from understanding the proteins encoded by the genes. Proteins not only make up the structural bulk of the human body but also include the enzymes that carry out the biochemical reactions of life. They are composed of unites called amino acids linked together in a long string: each string folds in a way that determines the function of a protein. The order of the amino acids set by the DNA base sequence of the gene that encodes a given protein, through intermediaries called RNA; genes that actively make RNA are said to be "expressed". The human gnome project seeks not just to elucidate all the proteins produced within a human but also to comprehend the genes that encode the proteins that are expressed, how the DNA sequences of those genes stack up ag
Within fifty years, scientists expect comprehensive genomies-based on health care to be the norm in the U. The tension between scientific advances and the desire to return to a simple and more "natural" lifestyle will probably intensify as genomic seeps in to mere and more of daily lives. Molecular biology has long held out the promise of transforming medicine from a matter of serendipity to a rational pursuit grounded in a fundamental understanding of the mechanisms of life. The challenge will be to maintain a healthy balance and to shoulder collectively the responsibility for ensuring that the advances arising from genomics are not put to ill use. Research of single cells will be research of the past. The drugs will target molecules logically and therefore be potent without significant side effects. Within the next half-century, wit all genes identified and all possible cellular interactions and reactions charted, pharmacologist developing a drug or toxicologist trying to predict whether a substance is poisonous may well turn to computer models to answer their questions. Scientist will have to examine how genes and their products behave in place and time that is in different parts of the body and in a body that changes over a life span. The modern humans originated in Africa and dispersed gradually into the rest of the world, race and ethnicity will prove to be largely social and cultural ideas; sharp scientifically based boundaries between groups will be found to be nonexistent. Then the members of the consortium plan to target representatives of each family for examination by pain staking physical techniques. ainst comparable genes of other species, how genes vary within the human species and how DNA sequences translate into observable characteristics. Many different amino acid sequences can lead to proteins of various proteins by studying a representative subset of proteins in detail. Another question asked is will the details of how genes determine mammalian development become clear? Being able to model a single cell will be impressive, but to understand fully the life-forms scientist are most familiar with, they will plainly have to consider additional levels of complexity. Within twenty year, novel drugs will be available that derive from a detailed molecular understanding of common illnesses such as diabetes and high blood pressure.
