What Are Genetically Modified Foods?
Genetically modified foods refer to crops and plants that have been transformed by molecular biology methods. Changes are made in these plants in the laboratory to develop selected characteristics such as augmented resistance to herbicides or enhanced nutritional value. Genetic engineering can produce plants with the precise preferred attribute very rapidly, and with immense accuracy. Plant geneticists can separate a gene accountable for drought tolerance, and install that gene into another plant, so that it will have increased tolerance to drought conditions. Genes can not only be transferred from one plant to another, but genes from non-plant organisms also can be used. The best known example of this is the use of B.t. genes in corn and other crops.
