Figure 4.

Centrosome division occurs in concert with the abortive attempt at mitosis in 1× CycB–only embryos. (A) 1× CycB embryos expressing GFP-Polo were injected with CycA and CycB3 dsRNA. Dashed circles highlight individual nuclei and associated centrosomes. Arrows point to paired kinetochores during the second successful mitoses. (B) 1× CycB embryos expressing TACC-GFP were injected with CycA and CycB3 dsRNA.
