Genetic engineering involves deliberately manipulating an organism's genes to produce a desired trait. It is done by transferring genes between organisms, such as inserting a gene from one species into a plasmid and introducing that plasmid into a host cell. Genetically modified foods have been produced since the 1990s and include soybeans, corn, canola, and tomatoes. While GM foods aim to create crops with advantages like pest resistance and increased yields, some argue they pose environmental and health risks.
