Genetically modified (GM) foods are foods obtained from organisms which its genetic material (DNA) has been changed in a way that does not transpire naturally. through the introduction of a gene from a different organism. Currently available GM foods stem mostly from plants, but in the future foods derived from GM microorganisms or GM animals are likely to be introduced on the market. Most existing genetically modified crops have been developed to improve yield, through the introduction of resistance to plant diseases or of increased tolerance of herbicides. Biotechnology is consist of a wide field of technologies and they can be applied for a range of different purposes. Genetic improvement of plant varieties and animal populations to increase their yields or efficiency and genetic characterization and conservation of genetic resources; plant or animal disease diagnosis; vaccine development; and improvement of feeds are some examples of biotechnology′s benefits.
