Mutagene; Mutagenic; Mutagens; Mutagenicity; Mutogen; Mutagenicity tests; Antimutagenic agents; Mutagenicity assays

mutagen

['mju:t?d?(?)n]

¦ noun a substance which causes genetic mutation.

Derivatives

mutagenesis noun

mutagenic adjective

Origin

1940s: from mutation + -gen.

Mutagen

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.

ORGANIZATION

Environmental Mutagen Society

The Environmental Mutagenesis and Genomics Society (EMGS) is a scientific society "for the promotion of critical scientific knowledge and research into the causes and consequences of damage to the genome and epigenome in order to inform and support national and international efforts to ensure a healthy, sustainable environment for future generations."

Mutagen

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. All mutagens have characteristic mutational signatures with some chemicals becoming mutagenic through cellular processes.

The process of DNA becoming modified is called mutagenesis. Not all mutations are caused by mutagens: so-called "spontaneous mutations" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.
