Many forms of electromagnetic radiation (e.g., cosmic rays, X rays, ultraviolet light) are mutagenic, as are a variety of chemical compounds.www.britannica.com/science/mutagenA mutagen is a chemical or physical agent capable of inducing changes in DNA called mutations. Examples of mutagens include tobacco products, radioactive substances, x-rays, ultraviolet radiation and a wide variety of chemicals. Exposure to a mutagen can produce DNA mutations that cause or contribute to certain diseases.www.genome.gov/genetics-glossary/MutagenMutagens, either endogenous or exogenous, increase genetic mutation probability. Endogenous mutagens, like reactive oxygen species (ROS), are produced by the body. Exogenous mutagens include intercalators and base analogs. Carcinogens lead to cancer, and while some are mutagenic, not all are. Examples include tobacco, asbestos, and UV radiation.www.khanacademy.org/science/ap-biology/gene-e… - People also ask
