Pros And Cons Of Genetic Engineering

2383 words - 10 pages

Genetic Engineering is highly controversial since some people believe that genetic engineering is playing God. As this fact there is opposition to the progression of the field by people who do not see the value in genetic engineering, or they fear what genetic engineering may lead to for us as people. There is a history of discover that belongs to genetic engineering, which has led to numerous products that have emerged which have brought numerous applications to the society of the world. Though there are benefits to genetic engineering, there are also drawbacks to genetic engineering including ethical and legal issues that are dealt with in today’s society in order to try and regulate the growth of genetic engineering.
Genetic engineering seems like a convoluted subject to broach. But in actually the form of genetic engineering practiced today is a more efficient method than what was practiced for hundreds of years which was selective breeding. Farmers, scientists, all ranges of humans practiced selective breeding which is just the intentional breeding of selective animals with desirable traits so that those traits are passed on and present in the offspring of those animals (Selective breeding).Genetic engineering is a streamlined version of selective breeding. Instead of choosing two organisms with desirable traits and compelling those organisms to mate with each other you can in take a splice of DNA, which is called gene splicing or recombinant DNA, and place it in a bacterium or a developing organism and you can produce the desired trait from the original organism in a completely different organism. With this process you could theoretically go as far as being able to develop a cow that has the DNA of a shark to develop gills and being able to survive under water. But the standard of genetic engineering today began more than a hundred years ago, when in 1859 Charles Darwin published the origin of species which was one of the first publications that gave extensive information on the subject or breeding at that time period (A brief history of genetic modification). Then the field advanced further when in 1865 Gregor Mendel published his discovering on the breeding of peas, which became a basis for the study of modern genetics. A more important discovery occurred in 1869 when Friedrich Miescher discovered nuclei, which is a major component in the formation of DNA, in the nucleus of a cell. In 1910 T. H. Morgan expanded the knowledge we have of chromosomes by demonstrating that genes are carried by chromosomes. Then in 1913 A.H. Sturtevant constructed a gene map giving people knowledge of where genes were located. Then in 1927 H. J. Muller demonstrated how X-rays could generate mutation in genes, expanding on knowledge that waves can affect the cells of organisms (A brief history of genetic modification). A major step forward in genetic engineering occurred in 1941 when George Beadle and E. L. Tatum managed to pin a gene defect to a single...
