Figure 7.
RTT107 and SLX4 make independent contributions to DNA damage resistance. (A) Ten-fold serial dilutions of cells were spotted onto YPD or YPD containing 0.03% MMS and incubated at 30°C for 3 d. (B) Logarithmically growing cultures were blocked in G1 with α-factor and released into media containing 0.04% MMS. Samples were withdrawn at the indicated times and plated on YPD to determine cell viability. The percentage of viable cells relative to the number of viable cells at t = 0 is shown. The average of three independent experiments is plotted.
