Figure 4From: The exceptionally high rate of spontaneous mutations in the polymerase delta proofreading exonuclease-deficient Saccharomyces cerevisiae strain starved for adenineGrowth curves of the strains de3-01-CG and of two Ade+ revertants on YEPD and SDNA+ade plates The number of cells/colony (fitness) on SDNA+ade (dotted lines) and on YEPD (continuous lines) is plotted against days in culture. We compared the strain de3-01-CG (triangles ▲) with two Ade+ revertants (strain 10, open circles ○; strain 15, closed circles ●).Back to article page
