Bub3+/-/Rae1+/- MEF showing two lagging chromosomes in anaphase. Mitosis was filmed from metaphase to late telophase. Frames were collected at 2-min intervals. The display rate is 1 frame/s. Chromosomes are visualized by ectopic expression of YFP-H2B (green). A micronucleus produced by one of the lagging chromosomes can be seen in late telophase.
