FIG. 4.

Intracellular distribution of DmORC-GFP in cellularized embryos. (A) Optical section of an embryo with asynchronously dividing cells. Nuclei in different stages of the cell cycle are marked: interphase (black arrow), metaphase (white arrow), late anaphase (white arrowheads), and telophase (black arrowheads). The scale bar is 20 μm. (B) Enlarged picture of a nucleus moving into metaphase. (C) Enlarged picture of a nucleus moving out of metaphase. For panels B and C, the scale bar is 5 μm and the elapsed time from the first picture is indicated. The color coding of the fluorescent proteins is as in panel A. Images in this figure are video stills taken from Movie S2 in the supplemental material.
