FIG. 2.
Radiation sensitivity of haploid mre11Δ and hdf1Δ strains. Asynchronous cultures and cells synchronized with α-factor (G1 synchronous) or carbendazim (G2 synchronous) were irradiated at a dose of 150 Gy as described in Materials and Methods. Cell survival was scored for 5 days following irradiation. Values plotted represent the average of triplicate platings from at least three experiments. Error bars represent standard deviations. Haploid strains were JPY70 (MRE11), JPY69 (mre11Δ), JPY181 (hdf1Δ), and JPY254 (mre11Δ hdf1Δ).
