Fig. 2. Polar body extrusion, ruffling and pseudocleavage fail in
ani-1(RNAi) embryos, but cytokinesis appears normal. Schematic
drawings of C. elegans early embryonic development (left column) and
selected images from timelapse DIC sequences of control (A-E) and
ani-1(RNAi) (A'-E') embryos. Embryo anterior is on the
left; posterior (defined by the site of sperm entry) is on the right. Arrow
indicates a polar body nucleus that has entered the embryo. Scale bar: 10
µm.
