mutagen

 [mu´tah-jen]
an agent that induces genetic mutation.

mu·ta·gen

(myū'tă-jen),
Any agent that promotes a mutation or causes an increase in the rate of mutational events, for example, radioactive substances, x-rays, or certain chemicals.
[L. muto, to change, + G. -gen, producing]

mutagen

/mu·ta·gen/ (mu´tah-jen) an agent which induces genetic mutation.

mutagen

(myo͞o′tə-jən, -jĕn′)
n.
An agent, such as a chemical, ultraviolet light, or a radioactive element, that can induce or increase the frequency of mutation in an organism.

mutagen

[myo̅o̅′təjən]
Etymology: L, mutare, to change, genein, to produce
any chemical or physical environmental agent that induces a genetic mutation or increases the mutation rate. mutagenic, adj., mutagenicity, n.

mu·ta·gen

(myū'tă-jen)
Any agent that promotes a mutation or causes an increase in the rate of mutational events, e.g., radioactive substances, x-rays, or certain chemicals.
[L. muto, to change, + G. -gen, producing]

mutagen

Any agent capable of changing the structure of DNA without immediately killing the cell concerned. Any surviving MUTATION may be perpetuated to all descendants of the cell. Mutagens include ionizing radiation such as ultraviolet light, X-rays, gamma rays and cosmic rays and a wide range of chemical substances including the tars in cigarette smoke.

mutagen

an agent that is capable of increasing the MUTATION rate in an organism, for example, X-rays, ultraviolet light, mustard gas.

mutagen

(mū´təjiən),
n a chemical or physical environmental agent that induces a genetic mutation or increases the mutation rate.

mutagen

a physical agent or chemical reagent that causes mutation to occur, e.g. x-irradiation, nitrous acid, and thereby increases the mutation rate of a gene.
