Genetically modified organisms (GMOs) have been around since the 1970s, yet they are often associated with plants or food. GMOs according to the literature ( Green, 2004, Phillips, 2008 ) are more than just food or plants. They have been linked to medicine, the environment, biological research, bacteria, virus and microorganisms. It contribution has been enormous, as such, I am of the view that it benefits far outweigh it disadvantages. Genetically modified organisms refer to plants, microorganisms and animals with an altered genetic make up that has been modified in the laboratory in order to incorporate genes from another organisms. WHO, ( 2014), states that this genetic material (DNA) has been altered in a way that does not occur naturally by mating or natural recombination. It is often called transgenic organism, genetically engineered organism, recombinant DNA technology, modern biotechnology, modern technology or gene technology. This modification enables scientist to find individual genes that control particular characteristics, separate them from the original source and transfer them directly into cells of an animal, plant, bacterium or virus. The use of GMOs has attracted considerable controversy namely food safety. However, significant benefits has been achieved through the use of GMOs in the field of medicine particularly pharmaceuticals. Genetically modified bacteria, plants and animals have revolutionised the production of vaccines. Safer, cheaper vaccines and drug products have been produced in genetically modified animal cells grown in the laboratory. For example, recombinant hepatitis B vaccine produced by GM yeast, insulin, produced in GM bacteria and factor V111 ( for hemophiliacs). it is evident, that countless lives have been saved all because of GMOs technique.
