Mutagen - Wikipedia
In genetics, a mutagen is a physical or chemical agent that permanently changes genetic material, usually DNA, in an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer in animals, such mutagens can therefore be carcinogens, although not all necessarily are.

2022年9月19日 · Mutagenesis is the process of an organism's deoxyribonucleic acids (DNA) change, resulting in a gene mutation. A mutation is a permanent and heritable change in genetic material, which can result in altered protein function and phenotypic changes.
Mutagens- Definition, Types (Physical, Chemical, Biological)
2023年8月3日 · Mutations occur randomly, i.e., not directed according to the organism’s requirements. Environmental factors cause most mutations, but they can also be created in the lab using chemicals, radiation, or physical stimuli. These mutagens may be carcinogens because numerous mutations can lead to cancer in animals, though not necessarily in all cases.

The meaning of MUTAGEN is an agent (such as a chemical or various radiations) that tends to increase the frequency or extent of mutation.
Mutagenesis - Wikipedia
Mutagenesis (/ mjuːtəˈdʒɛnɪsɪs /) is a process by which the genetic information of an organism is changed by the production of a mutation. It may occur spontaneously in nature, or as a result of exposure to mutagens. It can also be achieved experimentally using laboratory procedures.
