Fig. 4. Sequences of morphological changes during division on a solid substrate. Cells were attached to plastic dishes for 2 days before observation. Each panel shows a series of phase contrast images recorded with intervals of 60 seconds between frames. (A-E) Mitotic wild-type (A), mitotic mhcA^- (B), mitotic amiA^- (C), mitotic corA^- (D) and amiA^-/mhcA^- (E) cells. The cell cycle stage of the cell in E was not determined, but is most probably interphase. Bars, 10 µm. Magnifications of A-D are the same.
