Fig. 6. Morphology of wee1 conditional cells. (A) Wild-type and mutant cells in permissive and restrictive conditions. FB1 (wild type) and UMC23 (wee1^nar) cells were incubated for 8 hours in MMNO₃ or YPD and then stained with DAPI and FITC-WGA to visualize their nuclei and cell walls, respectively. Scale bars: 20 µm.
