Fig. 2. gpr-1/2(RNAi) embryos have similar phenotypes to those seen in G mutants. DIC images of live gpr-1/2(RNAi) and gpr-1/2(RNAi); gpb-1(RNAi) one-cell embryos recorded by time-lapse video microscopy undergoing the first division. Black arrowheads mark the current position of centrosomes. Short arrows mark the current position of the spindle poles on the AP axis during spindle elongation, and long arrows indicate the original position of the spindle poles before spindle elongation onset. White arrowheads indicate multiple nuclei. Note the lack of hyperactive nuclear rocking and lack of anaphase spindle pole oscillations (compare with Fig. 1). Relative time points are indicated (minutes:seconds). Scale bar: 10 µm.
