Cell division consists of nuclear division and cytoplasmic division.
Karyokinesis is the stage of nuclear division and divided into four stages; prophase, metaphase, anaphase and telophase.
Interphase is a stage prior to karyokinesis. It has three phase G1,S,G2. Replication of centriole occurs during G1-phase of interphase. DNA replication takes place in S-phase of interphase.
