WebAbstract. Mutations of numerous types can be induced in yeast. The basic principle is to bring the yeast in contact with the mutagen (UV light, X-rays, EMS, MMS, nitrous acid, nitrosoguanidine [NNG], ICR-170, nitrogen mustard, and so on), for long enough to bring about 50–95% killing, after which the mutagen is removed.
