Mitosis in cell division, animation

Videonummer 11942816
Animation of a cell dividing into two by mitosis. Mitosis is the process by which a cell divides its genetic material into two identical copies, and ultimately into two daughter cells. At the start of the process, structures called centrosomes (yellow) move to opposite ends of the cell. The nuclear membrane dissolves and the chromosomes condense and appear as long thread-like structures (prophase). They then align along the centre of the cell along the metaphase plate (metaphase). Each chromosome consists of two identical sister chromatids that separate and are pulled to opposite ends of the cell by microtubules along the mitotic spindle (anaphase). Nuclear membranes then form around the two daughter nuclei as the chromosomes de-condense (telophase). This is followed by cytokinesis, as the two new cells separate and form separate membranes.
