The 11 pages that link to Mutagenesis, each with the reason it gives.
DNA damageRelated: Unrepaired or incorrectly repaired damage can become a mutation.
CarcinogenicityRelated: Mutations can fix carcinogen-induced DNA damage into lasting changes.
Directed evolutionRelated: It creates the genetic diversity that selection can act on.
Alkylating agentRelated: Misreading or misrepair of alkylated bases can create mutations.
George BeadleRelated: Beadle and Tatum used X-rays to generate mutants for their nutritional tests.
NitrosamineRelated: DNA lesions from activated nitrosamines can produce mutations if unrepaired.
Ethidium bromideRelated: Intercalation can disrupt DNA replication and promote mutations.
