Figure 8.

Volumic visualization of an entire early telophase cell. (A) Chromosomes (blue) are less visible than during anaphase because of their fusing. (B) A stereo pair of a polar view shows the presence of a profound circular depression, lined by fusing chromosomes, which are separated by very deep furrows. (C) Median view of a set showing the presence of unfused chromosomes on this face. (D) Cutting one set in half shows evidence of its typical hollow half-sphere structure. (E and F) By rendering DNA transparent, NORs (yellow) appear clearly localized within the central part of the set disposed as a ring at the bottom of the depression (E). Bars, 2 μm.
