FIG. 4.
MMS sensitivity of S. pombe mutant for mag1 and NER. Logarithmically growing wild-type (WT; TE236), mag1 (AM006), rad13 (TE791), and mag1 rad13 (AM008) S. pombe strains were treated with the indicated dose of MMS for 1 h as described in Materials and Methods. Aliquots were collected and analyzed for colony-forming ability. The data shown are the mean and standard error of three independent experiments.
