A. Strains YOG3021 (SCC3-6HA scc3-6), YOG3024 (scc3-Y371A-6HA scc3-6) and YOG3025 (scc3-K372A-6HA scc3-6), were grown at permissive temperature (23°C) and arrested at G1 using α-factor. The cells were shifted to restrictive temperature (35.5°C) and re-arrested in the G2/M phase using nocodazole. Nuclei were spread and the bulk DNA was stained with DAPI. The morphology of the rDNA-loop of 100 nuclei of each strain was scored (n = 3). B. Representative photomicrographs of wild-type rDNA loops (left panel) and condensation defects at the rDNA locus. Arrow indicates the rDNA region.
