Before a new body cell or somatic cells can be made,  another identical copy of DNA must be made through a process called DNA replication.

The cell cycle describes the stages of what a cell must go through to during its life.

This includes most of its time in interphase, followed by the first gap phase, the S-phase and the second gap phase.

During each of these phases different processes occur in a cells life cycle.

Mitosis is a type of cell division for  growth, replacement and repair of body cells ( somatic cells).  It also is involved in asexual reproduction.
