title: A comparison of the response to 4CMB, 4HMB and BC of 5 yeast strains differing in their radiosensitivities.
abstract: The test compounds 4CMB, 4HMB and BC were assayed for their genotoxicity using stationary phase cultures of 5 yeast strains which differ in their mutagen sensitivity. It was found that 4HMB produced no differences in survival between the 5 strains whereas 4CMB and BC caused more lethality in the triple red strain than the other 4 strains. The results indicate that both BC and 4CMB are capable of inducing DNA damage which results in cell lethality in the repair-deficient triple mutant.
