Cytokinesis begins during which phase of cell division?

Telophase

During which stage of mitosis do nucleus reappear?

Telophase

If the chromosomes were not able to reproduce during the S phase of interphase, what would occur?

What is the purpose of cytokinesis?

To separate the cytoplasm and cell membrane
