The ultrastructural meiotic phenotype of the radiation sensitive mutant rad 6-1 in yeast


An ultrastructural analysis of three yeast rad 6-1/rad 6-1 diploids on sporulation medium for 0, 6, 10, and 24 h shows that arrest occurs at meiotic prophase. Two strains, CL 139 and PU 6, fail to complete chromosome synapsis based on the continued presence of single chromosomal cores in arrested nuclei. A clone derived from CL 139, however, showed complete… (More)
