When does cytokinesis typically begin and end? How is the cleavage furrow that divides the cell in half formed? What is the end result of the M stage of the eukaryotic cell life cycle?
Cytokinesis, which often begins during late anaphase with the formation of a cleavage furrow at the cell's equator (probably via a dense belt of actin and myosin filaments), is completed in telophase, as the furrow becomes progressively deeper until it finally divides the cell into two parts. Thus, the M stage of the eukaryotic cell life cycle concludes with the production of two genetically identical daughter cells, each with a full compliment of cytoplasm and cellular organelles as well as an exact replica of the mother cell's chromosomal matter.
