Pseudo images showing effects of rpb7T111I-H113D on TCR.A–L, bands reflecting CPD levels along the TS of AGP2, RPB2 and YEF3 genes in cells of indicated genotypes at the indicated repair times (min). ‘U’, sample unirradiated with UV. Numbers indicating the nucleotide positions of the genes are relative to the major TSS (+1). Note that panels A, C, E, G, I, and K, which serve as wild-type Rpb7 controls for comparison with Rpb7 mutants, are the same as Figure 3, A, C, G, I, M, and O, respectively.
