WebWhat is an example of an induced mutation? Induced mutations are alterations in the gene after it has come in contact with mutagens and environmental causes. Alkylating agents (e.g., N-ethyl-N-nitrosourea (ENU). These agents can mutate both replicating and non-replicating DNA. WebThey induce mutations especially transitions and transversions by adding an alkyl group (either ethyl or methyl) at various positions in DNA. Alkylation produces mutation by changing hydrogen bonding in various ways.
