Genetically Modified Organisms (GMO) is organisms whose genetic makeup has been altered through recombinant DNA technology, thus producing something different from the species. There exist various examples of genetically tailored organisms comparing transgenic animals, plants, fish, as well as microorganisms like parasites, fungi and bacteria. A particular example would be an introduction of the insulin gene of human into E. coli to give rise to human insulin. Nowadays, GMOs are developing and being used globally, in the U.S., most of their soybeans and corns are modified genetically (Carter, 2011).
Genetic modification of plants has been in use by farmers for many years. During the early farming, seeds of good producing crops were kept and preserved for use in the next season. Moreover, hybrids or crossbred plants have been established for various types of crops. Although, these plants are not recognized as GMOs since they are manipulated naturally, i.e. there is no recombinant DNA technique in introduction of new gene. There are various methods of introducing a gene into a plant. The common method uses agrobacterium, a genetic promoter and a soil bacterium from cauliflower mosaic virus. Other genetically tailored organisms (GMOs) are those resistant to drought or fungi, and those resistant to herbicides, thus delayed for ripening of fruits, therefore, increasing crop yield (Ahmed, 2002).
However, a number of people do object the use of genetically tailored
