Percent cell survival, displayed in log scale, in the parental strain (YB955) and cells containing single and double defects in Mfd and MutY, (YB9801, PERM1029, and PERM818, respectively), following exposure to tert-butyl hydroperoxide (t-BHP). Percent survival of each strain was determined by dividing the number of colonies from each of the test concentrations by the number of colonies observed in the no treatment. Means are shown for each strain. The error bars represent standard error. Means were compared using the SPSS software package and one-way ANOVA. To establish whether two means were significantly different, we used the least significant differnce (LSD) test (P < 0.05) between SPSS package. Means with the same letter are not significnatly different. ANOVA and and LSD tests were conducted within each of the t-BHP concentrations. These experiments were replicated four times, and each replicate experiment comprise of three repetitions. The total number of observations is 12
