sidebarA. Genetic engineering (GE) is the modification of an organismâs genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species.hese genes contain a unique set of instructions that determine how the organism grows, develops, looks, and lives. During genetic engineering processes, specific genes are removed from one organism and inserted into another plant or animal, thus transferring specific traits.
