Mutagen
From Wikipedia, the free encyclopedia.

A mutagen (Latin, roughly change maker) is an agent that changes the genetic information (usually DNA) of an organism and thus increases the number of mutations above the natural background level. Mutagens can be chemical compounds or radiation.

There are several methods to detect how mutagenic an agent is:

• Ames test
