Webby the Understanding Evolution team A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material WebExplanation: The correct answer is " site-directed mutagenesis " is not a source of natural genetic variation. This is because site-directed mutagenesis is a laboratory technique that involves intentionally introducing specific mutations into DNA sequences, and thus is not a naturally occurring process.
