- The use of recombinant DNA or other specific molecular gene transfer or exchange techniques to add desirable traits to plants, animals, or other organisms, or to enhance biological processes. Organisms modified by genetic engineering are sometimes referred to as transgenic, bioengineered, or genetically modified. The Agricultural Research Service does in-house research in this field, and the Animal and Plant Health Inspection Service regulates the release of genetically engineered organisms for field experiments.

- The manipulation of an organism's genetic endowment by introducing or eliminating specific genes through modern molecular biology techniques. A broad definition of genetic engineering also includes selective breeding and other means of artificial selection.
