  • Essay / Benefits of Genetically Modified Corn - 1324

    The world's population has surpassed six billion people and is expected to double in the next fifty years. Ensuring an adequate food supply for this burgeoning population will be a major challenge in the years to come (Burghart). Genetically modified (GM) corn is extremely beneficial for both farmers and consumers. Genetic engineering is a laboratory technique used by scientists to modify the DNA of living organisms. Genetically modified corn can benefit farmers by reducing costs and increasing crop yields. The new super corn can benefit consumers by producing healthier, more nutritious and more organic corn. Genetic engineers believe that scientific advances, like this one, will solve the global dilemma of starvation and hunger. Farmers began primitive genetic selection many years ago by selecting seeds from their best plants, replanting them, and gradually improving the quality of successive generations. (Johnson and Raven 238) Science has progressed since then. Scientists have developed insect-resistant corn. Crops that are resistant to insects and do not need to be sprayed with pesticides, many of which can harm the environment, are safer (Johnson and Raven 238). They are safer because the harmful chemicals used to spray crops will not be introduced into the environment. Biotechnology seems confusing and complicated at first glance, but it is actually quite simple. Biotechnology allows the transfer of only one or a few desirable genes from one organism to another. This precise science allows plant breeders to develop crops with specific beneficial traits and without undesirable traits (Monsanto Agricultural Biotechnology). The function and structure of DNA from different organisms are essentially the same. It is simply a site that gives instructions and directs cells to make the proteins that are the basis of life. Whether the DNA comes from a microorganism, a plant, an animal or a human being, it is made from the same materials (Monsanto Agricultural Biotechnology). A researcher's first step is to "cut" or remove a gene segment, representing a desirable trait, from a DNA string using enzymatic "scissors" to punch an opening in the plasmid, l he ring of DNA often found in bacteria outside the cell. The researcher then “glues” the gene segment into the plasmid. Because the cut ends of the plasmid and gene are chemically “sticky,” they attach to each other. To complete the process, researchers use another enzyme to glue the new one in place..
