Genetically modified foods (GM foods) are crops that are created for human or animal consumption by altering the genetic makeup of living organisms such as animals, plants, or bacteria. Modifying these organisms can enhance desired traits including an increased resistance to herbicides and improved nutritional content (Bren). GM foods have great potential but, at the same time, are causing much controversy.
There are four primary methods of gene transfer. One method, which is primarily used in animals, is called injection. The desired DNA is injected with a very small, sharp needle into the nucleus of a single cell (Whitman). This cell is usually a fertilized egg, which can then be placed back in the female uterus where the injected cell is allowed to develop normally. Unfortunately there is a high rate of failure when using this technique because cells infrequently take up and express the desired traits of the introduced DNA (Whitman).
