Table 1 Ts mutant frequency among: Ade⁺ revertants, Ade^- survivors and colonies from the log phase. The frequency of ts mutants in three independent experiments was estimated using a random sample of de3-01-CG Ade⁺ revertants, Ade^- survivors isolated on day 14 and Ade⁺ revertants obtained from exponentially growing cells. A hundred Ade⁺ revertants of the strain CG379-3-29(LR) starved for adenine were used as controls. The percentage of ts mutants with respect to the number of tested colonies is reported in parentheses.

From: The exceptionally high rate of spontaneous mutations in the polymerase delta proofreading exonuclease-deficient Saccharomyces cerevisiae strain starved for adenine
