Fig. 1. Prophase nuclear movements in wild-type, rec8 and rec7 mutant cells. Nuclei of strains (A) CRL 152 (wild type), (B) 57-2262 (rec8 mutant) and (C) 88-3485 (rec7 mutant) were stained with Hoechst 33342. Images were taken in a single optical section with 2 minute intervals. Numbers on the left of each image indicate time in minutes. In A, arrows indicate the position of the presumptive telomere cluster. In B, arrows indicate the position of the leading edge of the nucleus. In C, arrows indicate the position of the leading edge of the nucleus; the arrowhead points at the presumptive telomere cluster. Scale bar: 10 µm.
