Research Paper – Genetic Modification

Genetic modification is an important issue in the world today. As the human race progresses technologically, there are more doors opened to humanity. Some of these opportunities are for the better of mankind, others not so much. Genetic modification is one of those issues that can be argued both ways. It could be argued that genetic modification is the quickest and easiest way for the human species to adapt and learn how to cure a wide slew of diseases. At the same time, it could be argued that messing with genetic code was never intended to have been done by humanity and by doing so it endangers the entire ecosystem. Despite the side arguments genetic some aspects of genetic modification should be implored such as its methods, benefits, consequences, controversy, and oversight, or lack thereof.
According to Public Understanding of Biotechnology, genetic engineering is “the manipulation of genetic material (i.e., DNA or genes) in a cell or an organism in order to produce desired characteristics and to eliminate unwanted ones” (par. 5). This encompasses all living things, which is anything with DNA. Some of the types of genetic modification include gene therapy, genetic modification of food, and even cloning.
According to Wikipedia some of the benefits of genetic modification include: the production of disease and pest resistant crops, breakthroughs in gene therapy, and other uses such as the medicinal production of insulin (“GM” par. 8, “GM of Food” par. 1). Some other potential uses for genetic alteration according to Public Understanding of Biotechnology are allowing infertile parents to have children, replacing organs, and replacing lost children through cloning (Par. 21).
Farmers have used genetically modified crops to ensure the crop’s survival. In the state of Hawaii, farmers were able to create a disease and pest-resistant strain of taro, a plant that resembles a potato. This modification is also used in other crop species and is done so by splicing in certain genes from wheat and rice strains (Niesse par. 15). Genetically modified foods are not only limited to the Hawaiian Taro; there are a wide variety of other foods that are genetically modified. Wikipedia comments that several of these food strains are currently in use by the public. These products include, but are not limited to soybeans, corn, cotton, tomatoes, grape plants, sugar cane, sweet corn, and even rice (“GM Food” Par. 7).
Even though there are some benefits of genetic modification there are some repercussions, such as the controversy around cloning. These problems of cloning are, but not limited to, marginal success, chance of tumors, genetic defects, overgrowth syndrome, premature aging, lack of human knowledge on the topic, and probably most importantly the narrowing of the cloned and or genetically modified species’ gene pool. It is interesting to note that the success rate of cloning is three to four percent, leaving the other 96 to 97 percent with birth defects and tumors caused by the unstable embryonic stem cells. The successful three to four percent of clones are subjected to premature aging due to the fact that the age of a clone is determined by the original age of the donor and the sum of the clone’s age. It is also important to mention that cloning and other forms of genetic modification would narrow the selection of genes to that specie’s gene pool (PUB Par. 27). This might not have any adverse effects on the first few generations, but the fact remains that this would affect generations to come.
Some of the criticism on mankind tampering with nature’s use of genetic modification is that humans do not yet possess the knowledge to successfully edit the building blocks of nature. Another counter-argument that is expressed is that when one messes with a specie’s genes, one is playing God. While this argument might not hold much water, so to speak, with a non-religious person, there are other similar arguments that might.
For example, messing with specie’s genetic code could cause a decrease or a lack of genetic diversity in that specie’s gene pool (PUB Par. 27). By cloning some species, a species that is on the brink of extinction, there would be a lack of genetic diversity where previously there would have been a wider diversity if the original specie’s had not been cloned in the first place. This can be said because in the process of cloning, genetic material is only taken from one subject of the species, thus leaving just the genes that that subject carried with it. As a result, this would leave possibly hundreds of genes absent for future generations. While this might not be a big deal on a small scale, if one were to clone and entire species, this species would have nothing but the previous generation’s genes when it came time for the next generation. In conclusion when a disease eventually comes around that the species previously immune to, but that original ‘mother’ did not have an immunity to, then the entire species would be wiped out by that disease due to that lack of genetic material in that species gene pool.
As a result of these controversial concerns, one might ask Who oversees genetic modification? or What safeguards are in place? The answer to that question may surprise the reader. Certainty with all of the potential for misuse there must be a government administration in place to ensure that there is not any abuse or misconduct, right? Wrong. Unfortunately there does not appear to be a specific government organization in place for oversight. The only supervisions are a few lawmakers and the FDA, who monitors the genetic modification of food only. Genetically modified foods have been in the market since as early as May 1994 when Calgene, the company responsible for the production of the genetically modified tomato Flavr Savr, introduced Flavr Savr (“Flavr Savr” par. 1). Even now, most of the time the FDA is not worried about the long-term effects of genetically modified food; they are just concerned with the selling of it in the market place (Paynter par. 8).
While genetic modification is a ongoing issue in the world today, many people do not care to pay attention to it even though some of the possibilities of genetic modification will probably affect them in some way. Genetic modification continues to influence the world with the way that it is preformed, by its benefits and repercussions, its controversy, and its lack of oversight. This is why there needs to be a government or some other form of supervision put in place for the disease specific cases of genetic modification. So as to ensure that the genetic alteration of anything, not just food, is watched carefully to prevent potential catastrophes.
