Cell division: mitosis

All cells have a cycle that starts when they have been produced and ends when they divide to produce identical cells. Cell division is a small segment of the cell cycle. It is the process by which a parent cell divides into two or more daughter cells that can divide again. This division is known as mitosis. Before division can occur, the genetic information stored in chromosomes replicates and separates and the replicated genetic material in the parent cell  is equally distributed to two daughter cells.
