Metaphase cell division. Transmission Electron Micrograph (TEM) of a section through a HeLa cell during metaphase cell division (mitosis). At centre are chromosomes (dark structures); during metaphase the chromosomes line up in one plane in the centre of the cell,in preparation for nuclear division. The chromosomes are moved by spindle microtubules,fine straight lines leading to a centriole (dark circle,centre right). Organelles (white) are visible in the cytoplasm. During mitosis a cell produces two genetically identical daughter cells. HeLa cells are human cancer cells cultured in the laboratory and used in cancer research.
