Topic > Benefits of Genetically Modified Corn - 1324

The world population has surpassed six billion people and is expected to double in the next fifty years. Ensuring an adequate food supply for this booming population will be a major challenge in the years to come (Burghart). Genetically modified (GM) corn is extremely beneficial to both farmers and consumers. Genetic engineering is a laboratory technique used by scientists to modify the DNA of living organisms. GM corn can benefit farmers by reducing costs and increasing yields. The new super corn can benefit consumers by producing healthier, more nutritious and more organic corn. Genetic engineers believe that scientific discoveries, like this one, will solve the world's dilemma of hunger and starvation. Many years ago farmers began primitive genetic breeding by selecting seeds from their best plants, replanting them, and gradually improving the quality of subsequent generations. (Johnson and Raven 238) Science has come a long way 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 harmful chemicals used to spray crops will not be introduced into the environment. Biotechnology seems confusing and complicated from the outside, 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 characteristics and without undesirable characteristics (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 produce proteins that are the basis of life. Whether DNA comes from a microorganism, a plant, an animal or a human, it is made up of the same materials (Monsanto Agricultural Biotechnology). A researcher's first step is to "cut" or remove a genetic segment, representing a desirable trait, from a strand of DNA by using enzymatic "scissors" to cut an opening in the plasmid, the loop of DNA often found in all bacteria. outside of the cell. The researcher then "glues" the gene segment into the plasmid. Because the cut ends of both the plasmid and the gene are chemically "sticky", they stick to each other. To complete the process, the researchers use another enzyme to glue the new one into place.
