Genetic Engineering:
The technique by which genetic material from one organism is inserted into a foreign cell in order to mass-produce the protein encoded by the inserted genes. This relatively new technique manipulates the DNA (genetic material) of cells. For example, in this technique, the genes, which are actually portions of molecules of DNA, are removed from the donor organism (insect, plant, mammal, or other organism) and spliced into the genetic material of a virus; the virus is then allowed to infect recipient bacteria. In this way the bacteria become recipients of both viral and foreign genetic material.
