Delay and failure to complete DC shown in a time-lapse movie of a dib² mutant embryo expressing DE-cadherin-GFP. The dib² phenotype is indistinguishable from that described for spo^Z339 (see Movie S2). Each frame is a Z-stack projection. Elapsed time (h:min:s) is shown in the top right. Scale bar represents 20μm. Selected frames from this movie are shown in Fig. 1G,H.
