Technology Of Genetic Engineering example essay topic

A whooping 60% of what's on our supermarket shelves may contain genetically engineered soya. Some 3000 genetically engineered foods are lined up for approval. How should genetically engineered (GE) foods be regulated Foremost, we must clarify what genetic engineering is- laboratory technique used by scientists to change the DNA of living organisms. DNA is the blueprint for the individuality of an organism.

The organism relies upon the information stored in its DNA for the management of every biochemical process. The life, growth and unique features of the organism depend on its DNA. Genes are the segments of DNA, which have been associated with certain functions of an organism. Molecular biologists have discovered many enzymes, which change the structure of DNA in living organisms. Some of these enzymes can cut and join strands of DNA. Using such enzymes, scientists learned to cut specific genes from DNA and to build customized DNA using these genes.

They also learned about strands of DNA viruses- which can infect a cell and insert themselves into its DNA, so, scientists started to build viruses which made genes of their choosing and used the new viruses to insert these genes into the DNA of living organisms. Genetic engineers believe they can improve the foods we eat by doing this. For example, tomatoes are sensitive to frost, which shortens their growing season. Fish, on the other hand, survive in very cold water. Scientists identified a particular gene, which enables a flounder to resist cold, and used the technology of genetic engineering to insert this 'anti-freeze' gene into a tomato. This makes it possible to extend the growing season of the tomato.

A lot of food that we eat today contains genetically modified ingredients and usually without our knowledge. The biggest experiment in human history has begun, with us as the guinea pigs and the planets ecological system as the test site. The argument is not whether or not it should be allowed but how it should be regulated. Supporters of this technology want to ensure that people know what is real versus what isnt and so they want to enforce regulating labeling their products. Congress has provided the U. S Food and Drug Administration (FDA) a limited basis on which to require labeling.

Generally, for FDA to require labeling there must be something different about the food. In general, this means most genetically engineered foods will not need special labeling because they will be similar to the real thing, but there are exceptions, such as when a gene from a food that could cause an allergic reaction-peanuts, for example-is transferred into another food. In that case, FDA policy places the burden on the developer. "The food will have to be labeled so everyone will know it contains an allergen, unless the developer can show scientifically that the allergenicity has not been transferred", says Laura Tarantino, Ph. D., deputy director of FDA's Office of Pre-market Approval.

Fortunately, the products in front of us right now don't raise those issues". FDA also will require labeling if a company uses genetic engineering techniques to change a food's composition significantly. For example, when one manufacturer modified canola to produce increased levels of lauri c and meristic acids in the seed oil, FDA agreed that the common or usual name for this oil would be "lau rate canola oil" in order to distinguish it from traditional canola oil. People outside industry mainly, consumers, consumer organizations, environmental groups, independent scientists, European farmers, and public health organizations are the other players on the opposing side to this argument that states that genetically engineered products do not have a good track record for human safety. There are currently more than four-dozen genetically engineered foods and crops being grown or sold in the US. These foods and crops are widely dispersed into the food chain and the environment.

One example, for instance, was in 1989 and 1990, when a genetically engineered brand of L-tryptophan, a common dietary supplement, killed more than 30 Americans and permanently disabled more than 5,000 others with a potentially fatal and painful blood disorder, eosinophilia myalgia syndrome, before it was recalled by the FDA. The manufacturer, Showa Denk o K.K., Japan's third largest chemical company, had used genetically engineered bacteria to produce the over-the-counter supplement. It is believed that the bacteria somehow became contaminated during the DNA process. There were no labels on the product to identify the product as having been genetically engineered. According to the biotechnology industry almost 100% of US food and fiber will be genetically engineered within 5-10 years. The "hidden menu" of these unlabeled genetically engineered foods and food ingredients in the US now includes soybeans, soy oil, corn, potatoes, squash, canola oil, cottonseed oil, papaya, tomatoes, and dairy products.

Never again will people know the joy of eating naturally produced, fresh foods, so this is why some people believe GE foods should be wiped out in its entirety. Some members of the public seem prepared to take the risk. Contaminating most of our processed food is a risk imposed on us. I came to know about this problem when I heard about the numerous Kentucky Fried Chicken (KFC) urban legends. Rumor number one - KFC does not use real chickens.

They actually use genetically manipulated organisms. These so called "chickens" are kept alive by tubes inserted into their bodies to pump blood and nutrients throughout their structure. They have no beaks, no feathers, and no feet. Their bone structure is dramatically shrunk to get more meat out of them. This is great for KFC because they do not have to pay so much for their production costs. There is no more plucking of the feathers or the removal of the beaks and feet.

Rumor number two - the birds used by KFC are "so pumped up full of steroids, growth enhancements, and other chemicals, that the end result is no longer truly the meat of a 'chicken. Rumor number three - KFC genetically engineers mutant birds with 4 or more legs (drumsticks) apiece, thus increasing profitability. All of these urban legends have two main themes in common: alteration of the animals by chemical or genetic means and the prohibition from calling the resulting creatures "chickens". Legends KFC in particular are nothing new, as evidenced by the infamous "Kentucky Fried Rat" story, which has made the rounds for decades. The popularity of such rumors is attributable to the public's love of fast food restaurants and its distrust of large corporations in general. When I first singled out my topic, the only reason why I chose How should genetically engineered food be regulated was because I thought the KFC rumors were true and I thought that if KFC was going to sell their chicken then they should at least let the consumers know that it was not real chicken.

I thought these people must be brilliant to have thought of something as scholarly as making something exactly the way you want it, increase production while decreasing the unwanted. While surfing the web, looking up articles on GE foods in magazines, or watching the news to see if they had any vital information for my paper, I come to find out the dangers of GE foods are tremendous there are many health and environmental risks that come into play. Although people cannot even tell the difference, I feel as though if you are going to put a product on the shelf that causes some kind of health risk to the consumer in the future, it should be labeled for the consumer to make their own moral judgment on if they want to purchase it or not. I honestly didnt care in the beginning if something I was eating was genetically engineered or not. My mentality of thinking was that if it tastes like the real thing, then its acceptable to me. Now I come to the realization that maybe I should stop and take a look at what Im feeding myself.

Im afraid to get sick when I get older due to this genetic engineering phenomenon. I am afraid that if we let this continue then our children of tomorrow will have uncalled for diseases that man has yet to discover now that we have this new technology.
