Fig. 5. ida cells are aneuploid. Mitotic figures from
idak1-449 show examples of aneuploidy, with one cell
containing 21 unfragmented chromosomes (A), and another containing 39 (B).
Aneuploidy is also observed in null ida alleles. All individual
Hoechst-labeled chromatin figures in an ida
107 cell
(C) have a corresponding Bub1 antibody signal (D). Note that some of the Bub1
staining is not in the plane of focus.
