Dividing cancer cell. Coloured scanning electron micrograph (SEM) of a colorectal cancer cell undergoing mitosis (nuclear division) and splitting into two daughter cells (left and right). Here, it is in late telophase, the final stage before cell division (cytokinesis) and the two daughter cells are still connect by a cytoplasmic bridge (horizontal, centre). Bacteria (rod-shaped) can also be seen on the cells. Magnification: x2000 when printed at 10 centimetres wide.
