Mitosis in early embryos often proceeds at a rapid pace, but how this pace is achieved is not understood. Here we show that cyclin B3 is the dominant driver of rapid embryonic mitoses in the C. elegans embryo. Cyclins B1 and B2 support slow mitosis (NEBD to Anaphase ~600s) but the presence of cyclin...
