Genetic engineering -

GENETIC ENGINEERING Scientists are trying to figure come to the fore the good three billion-letter world genome with high precision as a prelude to figuring out eventually what protein each(prenominal) broker produces and for what purpose. It all started in 1866 when Austrian botanist and monastic Gregor Mendel proposed sanctioned laws of heredity based on crossbreeding experiments with pea plants. His findings, publish in a local natural-history journal, were largely ignore for to a greater extent than thirty years. In 1910 U.S. life scientist Thomas Hunt Morgans experiment with fruit go reveal that some transmissibleally determined traits are sex linked. His realize also confirms that the genes determine these traits reside on chromosomes. It continuos until 1997 when researchers at Scotlands Roslin Institute, led by embryologist Lan Wilmut, reported that they cloned a sheep-named Dolly-from the cadre of an adult ewe. The near goal of scientists is to sequence all human deoxyribonucleic acid by 2003, the Human Genome Projects current tar attempt date (Lemonick 46). But we should intention genetic design in a proper way. Our goal should be to find areas where it is call for rather than try to molest it for personal gain. Genetic engineering dirty dog provide health check benefits to humans, but limits nonplus to be set.

The Code of Life Our form contains one c trillion cells, inside most cells is a nucleus that contains a complete set of the bodys blueprints. Those blueprints are twisted into forty-six packets called chromosomes. Unravel a chromosome, and y ou get the long, thread-like molecule called! DNA. deep down the DNA are the blueprints, called genes, for which make proteins. The DNA molecule has a twisted, laddershaped structure (the famous double helix). The genetic encrypt can be read in the rungs of the ladder. The code is spelled out by four chemicals: adenine (A), thymine (T), gigabyte (G), and cytosine (C). A pairs...
