Genetic Engineering
Genetic engineering is a technique used by scientists to transform the DNA (deoxyribose nucleic acid) 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 group of every biochemical process. The life, growth and unique features of the organism depend on its DNA. The sections of DNA which have been associated with specific features or functions of an organism are called genes. 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 these enzymes, scientists learned to cut the specific genes from DNA and to build customized DNA using these genes. They also learned about vectors that are strands of DNA such as viruses, which can infect a cell and insert themselves into its DNA. Scientists soon began to construct vectors which inserted specific pre-chosen genes into the DNA of living organisms. The job of the Genetic Engineer today is to improve certain aspects of living organisms to prevent diseases or
the break down of the cells within. One example is seen in the food industry, for example, the tomato. The tomato is known to have a short growing season because of it's sensitivity to frost. Genetic Engineers were able to locate a gene in a fish that allows it to survive the cold water and then inserted this frost resistant gene into the tomato. Therefore the tomato can grow for a longer time, allowing the consumer to choose bigger and juicier tomatoes. In conclusion genetic engineering can have both a positive and a negative effect. Growing of more crops for less is definitely positive, however scientists are not accurate on how agricultural engineering can be absolutely safe for our society. In my opinion we perform individual responsibilities everyday in life that is dangerous and harmful to our bodies and our environment. These responsibilities can have a negative and a positive effect, therefore if we add another harmful aspect into our lives, will it make more of a difference? I think that it might.
