mutagen
DNA alteration agent
A mutagen is an agent that causes genetic mutations—changes to DNA that can be inherited or lead to disease.
Radiation, certain chemicals, and some viruses are mutagens.
The term appears most often in scientific and medical contexts: The study tested common household chemicals for mutagenic properties.
Carcinogens are often mutagens, though the terms aren't synonymous.
