FIG. 6.

A reduction in the level of Pol3p reduces cell viability in the absence of Rad52p. Fivefold serial dilutions of strains RJK396 (POL3 RAD52; top row of each panel), RJK397 (POL3 rad52Δ; second row), RJK398 (GAL1-POL3 RAD52; third row), and RJK399 (GAL1-POL3 rad52Δ; bottom row) were spotted onto plates containing the indicated medium. All four strains were derived from the same tetrad following sporulation and dissection of diploid strain RJK372. The growth pattern shown here is identical to that from two additional tetrads of the same genotypes.
