Figure 5.

Requirements of error-prone and error-free bypass pathway components for two-strand mutations in nondividing cells. Induction frequencies of pure white (open bars) and red-white sectored (red cross-hatched bars) ade2 adeX mutants in G0 populations of cells are shown. Asterisks above the bars indicate a lack of UV-induced mutagenesis (irradiated to unirradiated sample comparison, P > 0.1 in all cases).
