title: Effect of X-irradiation on frameshift and missense mutations in Saccharomyces cerevisiae.
abstract: In cell populations of Saccharomyces cerevisiae homogeneous for sensitivity to X-irradiation, induction of base insertions/deletions and base substitutions was quantitatively analyzed in a reversion system. The repair mechanisms phenotypically unexpressed in the sensitive cell fraction and fully operating in resistant cells did not affect point mutations of either type.
