Figure 7: UV-induced direct repeat recombination in exo1∆ and rqh1∆ single and double mutants.

(a) UV survival curves for strains MCW429, FO949, FO911 and FO1098. The error bars are the standard deviations about the mean. (b) UV-induced Ade+ recombinant frequencies for the same strains as in (a) (see also Supplementary Table S2). Data are represented as mean ± standard deviation. Where a bar extends beyond the scale on the Y axis the value is indicated by the number in the bar.
