Mitotic cell division. Comparison between a scanning election micrograph (SEM left) and transmission electron micrograph (TEM right) of a cancer cell dividing by mitosis, the asexual replication of a cell into two new daughter cells.This is late telophase, the fourth stage of mitotic division, when the cell's genetic material ( dark blue TEM) has been separated via the spindle (centre) into two identical populations. The nuclear membranes have reformed around the genetic material (TEM) and the process of cytokinesis, the separation of the two new daughter cells, will shortly occur. Magnification: x10000 at 10 centimetres wide. For a series of comparisons between SEMs and TEMs see images C047/7006 to C047/7034.
