Genetically modified organisms are organisms that’s genetic material has been changed using engineering techniques. Organisms that are genetically modified include microorganisms such as bacteria and yeast, insects, plants, fish, and mammals. This alteration of the genes usually entails inserting genetic material into an organism in a laboratory without natural mating, breeding or reproduction. Instead of breeding two plants or animals together to bring out certain traits in the offspring, the plant, animal or microbe has DNA from another organism inserted. Creating GMOs is one type of genetic engineering. Because we have Genetically modified organisms, it has opened a whole new way of thinking in life. In this article we will be talking about gene therapy, and the pros for genetically modified organisms.

Genetic modified organism can be used in the medical field. Gene therapy is an example of that. So what is this mystical new wonder called gene therapy? Gene therapy is the introduction of genes into existing cells to prevent or cure a wide range of diseases. “For example, suppose a brain tumor is forming by rapidly dividing cancer cells. The reason this tumor is forming is due to some mutated gene. The therapy chosen for this case would be to use a herpes virus that has had its virulence removed, rendering it harmless. The virus is still able to insert its genetic material into the target cells. The virus is then taken and injected into mouse cells, where it makes additional copies of itself. These mouse cells, now containing the virus, are then injected into the brain containing the tumor. Once inside the brain, the virus seeks out the target tumor cells and invades them. The tumor will now start to produce herpes enzymes because the virus has inserted its genetic material into the tumor cells.” It helps people. Gene therapy has cured hundreds, if not thousands of diseases, that without gene therapy would not be possible. At this very moment, they are...
