Genetically Modified Organisms Essay

Genetically modified organisms or GMOs are organisms whose genetic material has been modified using recombinant DNA methods. Modern recombinant technologies enables DNA segments from different organisms to be held together. Organisms have been genetically modified in laboratories for purposes such as to study gene functions, replicate genes or proteins, or create models to cure human diseases. One of the most important application of GMOs is to generate crops that encodes for pest resistance. The use of genetically modified organisms has both positive and negative effects on humans and the environment.

Genetically modified organisms or GMOs are organisms in which a gene from one organism is altered to contain a segment of DNA from another organism. Transformation is a natural process in the cells that introduces DNA from an outside source into the cell. The process of genetically modifying an organism is an artificial form of transformation that introduces foreign DNA into cells using modern technologies. A transformed cell that can be used to form all or part of an organism, is called a genetically modified organism.

Through the process of selective breeding, a desirable trait can be produced in a plant or an animal. However, with the introduction of genetically modifying techniques, selective breeding is done in laboratories. Genes that express a desired trait is physically moved and added to produce that certain trait in the organism. Breeders sometimes have to cross many plants over multiple generations to produce the desired trait. Genetically modifying techniques allow new traits to be introduced one at a time without complications. In a similar process, scientists have been able crops that can encode for pest or herbicide
