Cell Division (Mitosis) is the division of a cell to form two identical daughter cells. Before a cell divides all of the genetic material contained in DNA must be accurately replicated in a process called DNA replication. After replication the cell then has two copies of its DNA. When the cell divides the DNA is split equally between the two daughter cells. These cells then go on to DNA replication and division and so on. Cells are continuously replicating and dividing.
