Genes are, basically, the blueprints of our body which are passed down from generation to generation. Through the exploration of these inherited materials, scientists have ventured into the recent, and rather controversial, field of genetic engineering. It is described as the "artificial modification of the genetic code of a living organism", and involves the "manipulation and alteration of inborn characteristics" by humans (Lanza). Like many other issues, genetic engineering has sparked a heated debate. Some people believe that it has the potential to become the new "miracle tool" of medicine. To others, this new technology borders on the realm of immorality, and is an omen of the danger to come, and are firmly convinced that this human intervention into nature is unethical, and will bring about the destruction of mankind (Lanza).
Although humans have altered the genomes of species for thousands of years through artificial selection and other non-scientific means, the field of genetic engineering as we now know it did not begin until 1944 when DNA was first identified as the carrier of genetic information by Oswald Avery Colin McLeod and Maclyn McCarty (Stem Cell Research). In the following decades two more important discoveries occurred, first the 1953 discovery of the structure of DNA, by Watson and Crick, and next the 1973 discovery by Cohen and Boyer of a recombinant DNA technique which allowed the successful transfer of DNA into another organism. A year later Rudolf Jaenisch created the world’s first transgenic animal by introducing foreign DNA into a mouse embryo, an experiment that would set the stage for modern genetic engineering (Stem Cell Research). The commercialization of genetic engineering began largely in 1976 wh...
