Question

What is the Purpose of Cytokinesis?

Answer 1

Cytokinesis:

1. The division of the cytoplasm that occurs following the duplication of chromosomes during cell division is termed cytokinesis.
2. Once the nuclear divisions have occurred (whereby the genetic material is duplicated), the cytokinesis of the parent cell takes place.
3. This results in the division of the parent cell's cytoplasm to form two daughter cells.
4. The process begins with the development of a cleavage furrow at the equatorial plane of the parent cell.
5. This is mediated by the cytoskeletal proteins present in the cytoplasm.
6. As the furrow deepens, the cytoplasm is separated to form two separate cells.
7. Cytokinesis occurs in mitosis at the end of telophase and in meiosis II at the end of telophase II.
