Plots showing effects of rpb7T111I-H113D on TCR.A and B, means of percent CPDs remaining at all CPD sites 50 nucleotides downstream of the major TSS in the TS of AGP2, RPB2, and YEF3 genes in cells with the wild type and mutant Rpb7. ∗∗ and ∗ indicate p values < 0.01 and 0.05, respectively, at the respective repair time points (paired Student’s t test). The values for the wild type and mutant Rpb7 were paired with respect to the AGP2, RPB2, and YEF3 genes for the Student’s t test.
