The Pros And Cons Of Genetic Engineering

Genetic engineering has become a very popular field in biotechnology over the past decade and many scientists have made it their topic of interest. Ranging from food to health care, applications of gene technologies have become a part of our daily lives. Just like other technologies have in the past and still do raise social and ethical issues, genetic engineering does too. The main focus of genetic engineering is on the DNA molecules and specifically on the genetic information it encodes. In order to genetically engineer a DNA molecule, you must change the information it contains by removing, altering, or adding genes. The letters DNA stand for deoxyribonucleic acid and it is made up of four different subunits called nucleotides. These bases are called adenine, guanine, cytosine, and thymine. The DNA sequence in a gene can be translated into the sequence of amino acids in a protein. A positive use of genetic engineering could be in preventing deadly illnesses in children. As explained in the article, “Controversial Genetic Engineering…Children” by Barry Starr (Glossary of Biotechnology Terms), a woman who would pass a certain fatal genetic disease to her child could be prevented by a simple genetic engineering procedure. All that is required is for a tiny snip of DNA to be replaced with that of another egg donor and the disease would not be passed along to future generations. This procedure can only help women who carry a certain mitochondrial disease. This refers to a cell lacking the production of energy that, if continued (Schenone) (Black, Edwin;) (Davis)disease due to mutation(s) in her mitochondrial DNA would be able to benefit. Usually it is taboo to modify information that can be passed on to the next generation. Wit... ... middle of paper ... ...a repressive and racist ideology. The opposite of this movement would be to let natural selection run its course. In this way, there would be a variety of characteristics put to the test. If there was only a specific number of traits left circling in the world, there is no way of knowing if those selected traits are the ones that are best fit for any given environment. This is why variation is so important. Genetic engineering is an interesting topic that has come a long way and yet has much more to go. Some would argue that the future is not in need of these technological advancements and others would say the opposite. Perhaps the world would be better off predicting and preventing diseases, but still the misuse of biological findings could be devastating. There is still much to be debated and as biotechnology advances, much more will continue being debated on.
