A new technique which removes all membranes, cytoskeletal elements, organelles, but preserves intact metaphase, anaphase and telophase configurations is combined with scanning electron microscopy (SEM) as an approach for direct visualization of chromosomal behavior in late mitosis. With this approach we are able to confirm the presence of a centromeric ring which stabilizes the centromeres during the cell cycle and present evidence for a lattice-like sheet of interchromatidic fibers in late mitosis. |
