Abnormal mitosis. Fluorescence micrograph of a cell during an abnormal metaphase of mitosis (cell division). During mitosis,two daughter nuclei are formed from one parent nucleus in a cell. This requires organisation of the chromosomes (blue) and mitotic spindles (green) to ensure that each cell retains an exact copy of the parent cell's genetic information. Usually at metaphase the cell chromosomes form a vertical line and the spindles form a symmetrical structure either side. In this cell,the chromosomes are not assembling properly,and four spindle poles have formed (tetrapolar mitosis). Abnormalities or cell death can result | |
