FIG. 7.
The mre11-58S mutant is as sensitive to MMS as mre11-58. Haploid strains HTY1114 (mre11-58S), HTY693 (mre11-58), HTY1075 (mre11 null), and NKY1003 (rad50S), and a wild-type strain (HTY464) were grown in YPD liquid medium, diluted appropriately, spread on MYPD plates containing various concentrations of MMS, the plates were incubated at 30°C for 5 days, and the numbers of colonies growing on each plate were counted.
