Medical Definition of DNA amplification

DNA amplification: The production of multiple copies of a sequence of DNA. Repeated copying of a piece of DNA.

DNA amplification plays a role in cancer cells. A tumor cell amplifies, or copies, DNA segments as a result of cell signals and sometimes environmental events.

Amplification can occur in vivo (in the living individual) or in vitro (literally "in glass", or in a plastic vessel in the laboratory).
