title: Genetic activity of chemicals in yeast: DNA alterations and mutations induced by alkylating anti-cancer agents.
abstract: The simple eukaryotic organism baker's yeast allows demonstration of primary DNA lesions in parallel with measurement of mutagenicity and lethality after treatment with alkylating chemicals. Several anti-cancer drugs formed cross-linked DNA molecules and were genetically active. The mutagenicity and lethality of these drugs varied substantially and were dependent on the function of some processes of DNA dark-repair.
