The cell cycle is the life of a cell from the time it is first formed from a dividing parent cell until its own division into two cells. Cell division involves the distribution of identical DNA to two daughter cells. A dividing cell duplicates its DNA, allocates the two copies to opposite ends of the cell, and then splits into daughter cells. The replication and distribution of so much DNA is manageable because the DNA …

…the centrosomes, the spindle microtubules, and the asters. . At metaphase, the centromeres of all the duplicated chromosomes are on a plane midway between the spindle's two poles. This imaginary plane is called the metaphase plate of the cell. At the end of anaphase, duplicate groups of chromosomes have arrived at opposite ends of the elongated parent cell. Nuclei re-form during telophase. Cytokinesis generally begins during these later stages of mitosis, and the spindle eventually disassembles.
