Alterations in error-prone DSB repair in NG and G0 cells. a) Mean Lys⁺ frequencies and revertant-type distributions in growing, NG and G0 cells. b) Mean survivor frequencies and event-type distributions in growing, NG and G0 cells. Error bars are 95% confidence intervals for mean frequencies. Event-type distributions were compared to growing cells using a 2 × 4 or 2 × 3 contingency chi-square test for revertants or survivors, respectively; ns, not significant. If the global P-value was <0.05 (above each spectrum), then individual mutation types were compared using the Bonferroni correction to determine significance; asterisks indicate a significant proportional increase/decrease.
