Mitosis (image 4 of 6). Digital three-dimensional immunofluorescent light micrograph of a section through a mammalian cell during the anaphase stage of mitotic cell division. The two chromatids that form each chromosome (blue) are being pulled to opposite ends of the cell. The actin microfilam- ents (red) and tubulin microtubules (green) of the cytoskeleton maintain the cell's structure. The two centrosomes (pink dots, centre left & right) organize the microtubules that move the chromosom- es around the cell. Mitosis produces two identical daughter cells. This is a rat kangaroo kidney epi- thelial cell. Magnification: x500 at 6x7cm size. For a sequence of mitosis see images P673/052-057.
