Examples of anaphase S2 cells. a Early anaphase cell showing initial separation of the sister chromatids. Note the kinetochores of the separating sister chromatids (arrowheads) and the vesicles at the spindle poles. b Mid/late anaphase. Note the formation of a double membrane around the chromosomes (arrowheads) and the MT bundles in the center of the cell. Asterisks indicate the cell regions shown at higher magnification in the central and rightmost images. Scale bars: leftmost image, 5 μm, central and rightmost images, 1 μm
