Fig. 2. Nuclear dynamics during the first meiotic division in the rec8 and
rec7 mutants. (A) rec8 mutant. Nuclei of strain 57-2262 were
stained with Hoechst 33342. Numbers on the right of the images indicate time
in minutes. (B,C) rec7 mutant. Nuclei of strain 88-3485 were stained
with Hoechst 33342, and two divisions with different outcome were chosen for
presentation. Numbers on the left of the images indicate time in minutes. In
case of division (B), chromosomes were apparently unevenly distributed between
the daughter nuclei. (C) Division resulted in even segregation. Equal numbers
of chromosomes moving to opposite poles are clearly discernable at 48 minutes.
The arrow indicates a chromosome moving between two poles. Scale bar: 10
µm.
