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. Magnification: x9,175 at 8x10 inch size.
