Fig. 3.

(A) The initial and final configuration for a spherical embryo. The NCC centers but fails to rotate. (B) The initial and final configuration for an embryo with a single centrosome (Movie S6). NCC positioning and orientation are disrupted. (C) Position of NCC along the AP axis. (D) Angle of NCC to the AP axis. The vertical dashed line indicates time of centration. (E and F) Net cytoplasmic drag force/torque computed in the present model (accounting for the enclosing cell geometry) compared with drag/torque estimated by Stokes law (assuming an open geometry). Red lines are the raw data, and the blue and black lines are moving averages, shown for clarity.
