The division of a parent cell into two identical daughter cells does not occur during any of the phases of mitosis. Rather, this physical separation occurs during cytokinesis, a process that takes place right after mitosis.
Mitosis involves the division of the nucleus of a cell. It is divided into five phases: prophase, prometaphase, metaphase, anaphase and telophase. Cytokinesis, which involves the formation of a cleavage furrow, occurs after telophase.
During cytokinesis, the parent cell that now contains two sets of chromosomes enveloped by their own nuclear membranes, is cleaved at the equator. This process is driven by the constant shifting of myosin and actin filaments. As a result of this movement, the parent cell splits into two daughter cells.
