Something that is capable of mutating DNA. Among the known mutagens are radiation, certain chemicals, and some viruses.

(myoot-uh-jen) [L. mutare, to change + genus, source or origin] A chemical or physical agent that interacts with DNA and causes a mutation.

Agent that can induce heritable changes (mutations) of the genotype in a cell as a consequence of alterations in or loss of genetic material.

Mutagène

The term for a type of agent that works with DNA to create a change in the makeup of a cell

1946, from mutation + -gen "thing that produces." Related: Mutagenic; mutagenesis; mutagenize.

A mutagen is a chemical or physical phenomenon, such as ionizing radiation, that promotes errors in DNA replication. Exposure to a mutagen can produce DNA mutations that cause or contribute to diseases such as cancer.

Any physical or chemical agent that significantly increases the frequency of mutational events above a spontaneous mutation rate.

A substance that induces mutations.

A chemical that can cause changes in the sequence of DNA.

An agent that increases the frequency of mutation.

An agent that is capable of increasing the mutation rate.

A material that alters a cell's genetic information (DNA) and may lead to undesirable inherited conditions in progeny.

An agent that causes mutations.

An agent (e.g., X-rays, gammarays, mustard gas) that can induce MUTATION.

Any agent that increases the frequency at which DNA is altered (mutated).
