Description

Transmission electron micrograph of cell division in an insect spermatocyte captured in late anaphase - telophase with cytokinesis in progress. The homologous chromosomes appear as darkly stained disc-shaped profiles within each daughter cell, being separated by the cleavage furrow.

Technical Details

Micrograph courtesy of David Phillips, Figure 127 from Chapter 4 (Nucleus) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. A PDF copy of the accompanying chapter is available on the ASCB's BioEDUCATE website.
