Usage

The word "mutagen" is used to describe an external factor or substance that causes genetic mutations. It is a technical term primarily used in biology, genetics, toxicology, and medicine. * Certain chemicals are known to be powerful mutagens. * Ultraviolet radiation from the sun is a natural mutagen. * Scientists test new compounds to determine if they are mutagens.

Examples
  • In a laboratory context:
  • In a public health context:
  • In a biological explanation:
Advanced Usage
  • Mutagenicity (noun): The property or capacity of an agent to cause mutations.
    • The mutagenicity of the compound was confirmed by the Ames test.
  • Mutagenic (adjective): Having the ability to cause mutations.
    • The substance was found to be highly mutagenic in bacterial assays.
Variants and Related Words
  • Mutagenesis (noun): The process or event of generating a mutation; the formation of mutations.
