During Which Phase of Mitosis Does a Cleavage Furrow Begin

Question

During which phase of mitosis does a cleavage furrow begin to appear?
A) telophase
B) anaphase
C) metaphase
D) interphase

Accepted Answer

A cleavage furrow begins to appear during telophase, which is the final phase of mitosis. During telophase, the chromosomes have moved to opposite ends of the cell and the nuclear envelope starts to reform around them. The cell membrane then begins to pinch inwards at the center, creating a cleavage furrow that divides the cytoplasm and ultimately results in two daughter cells.
