KIN-3 is required for proper cell division. 4D time-lapse movies of embryos expressing mCherry::plasma membrane and mCherry::histone. Compared to control (L4440), kin-3(RNAi) results in abnormal chromosome segregation and delay in cell cycle progression. Movies are taken 60 sec interval. Time is relative to the first metaphase (t=0) and shown in hh:mm. Note that movies do not begin at the same cell cycle stage due to a delay in cell cycle progression in the kin-3(RNAi) embryo. 5 fps. Scale bar, 5 μm.
