Christine GENETICALLY MODIFIED ORGANISM

Genetically Modified Organism by CHRISTINE E. YANTO in NAT.SCI (BIOLOGICAL SCIENCE) Submitted to: Ms. Ma. Kahtrina Pobre

introduction The term “genetically modified organism” does not always imply, but can include, targeted insertions of genes from one species into another. Genetically modified organism contain no DNA from other species and are therefore not transgenic but cisgenic. They are use in biological and medical research, production of pharmaceutical drugs, experimental medicine (e.g. gene therapy), and agriculture (e.g. golden rice).

Genetically modified organisms or GMOs, are living organisms that have been altered through genetic engineering. The purpose creating GMOs is usually to combine beneficial genes of different organisms in a single organism often for the purpose of consumption as a food source. Using GMOs in agriculture has many potential benefits.

ADVANTAGES OF GENETICALLY MODIFIED ORGANISM

[object Object],One of the most important benefits of GMOs is their potential for adding to the healthiness and natural resistances of organisms. GMOs can potentially be created that have greater resistance to insect infestation and plant diseases. For instance, a certain strain of corn might produce a large amount of food tonnage, but be susceptible to insects, while another might repel the insects but produce a low amount of raw food tonnage. If the insect resistance of the lower yield plant were combined with the higher yield plant, a new GMO could be made that provides a large amount of food and resistance to insects. Another benefit of increased plant resistance is that it has the potential to reduce the amount of chemicals used on plants to protect against insects and disease, which can reduce pollution introduces to the environment.

[object Object], Some plants are susceptible to being overrun or choked out by weeds that compete for the same nutrients. Another benefit of GMOs is the potential to increase the chemical resistance of food crops, allowing herbicides to be used that will harm any weeds, while leaving the desirable crop relatively unaffected. This, in turn, can increase crop yields.

[object Object], GMOs are especially important for developing countries where simple nutrition is of utmost concern. GMOs provide a potential for increasing the nutritional value of plants. For example, a region might rely heavily on a certain crop such as rice or corn, which may not have all the various vitamins and minerals necessary for proper nutrition. A plant that normally offers little or no vitamin A might be combined with the genes of another plant that is high in vitamin A. GMOs can introduce new sources of essential nutrients which can fight health problems caused by nutrient deficiencies.

[object Object], The benefits of GMOs can have an additional affect of increasing the profitability of farming. Having plants that are better able to resist various maladies can increase crop yields while reducing the amount of money spent on efforts to protect the plants. According to Monsanto.com, farmers made an additional $10 billion in 2007 from planting GMOs, which is due to increased yields and reduced production costs.
