Abstract

Mutants of Chinese hamster ovary cells that are resistant to α -amanitin can be isolated. At least some of these mutants contain an altered form of DNA-dependent RNA polymerase II, as indicated by its resistance to α -amanitin. These results indicate that mutation to α -amanitin resistance involves a change of a structural gene.
