Mutagenesis may occur endogenously (e.g. spontaneous hydrolysis), through normal cellular processes that can generate reactive oxygen species and DNA adducts, or through error in DNA replication and repair. Mutagenesis may also occur as a result of the presence of environmental mutagens that induce changes to an organism's DNA. The mechanism by which mutation occurs va… WebAbstract. Important methods to artificially induce mutations are the use of chemical and physical agents. Most chemical mutagens are alkylating agents and azides. Physical mutagens include electromagnetic radiation, such as γ rays, X rays, and UV light, and particle radiation, such as fast and thermal neutrons, β and α particles. chris king bottom bracket gxp
