Mitosis. Image 6 of 6. Coloured scanning electron micrograph (SEM) of two breast cancer cells formed by mitotic cell division. During mitosis, the nuclear material of a cell divides so that two identical nuclei are formed at opposite ends of a single cell. Cytokinesis completes the process by separating the cytoplasm and cell organelles to form two independent, but genetically-identical daughter cells. Magnification: around x2200 when printed 10cm wide. For a sequence of mitosis, see images P672/088 to P672/093.
