GFP-γTub and H2A-RFP from NC 12 interphase to NC 14 interphase in a control embryo. Live control Drosophila embryo expressing GFP-γTub (green) and H2A-RFP (red). Frames were captured at 20 s intervals over 31 min 40 s using a 1 μm z-step size over 14 μm total depth. Video displayed using a playback speed of 6 FPS (frame per second). Still images are shown in Fig. 8A. Bar: 10 μm.
