Cytoplasmic division or cell division begins during anaphase of mitosis and continues as the cell pinches into two new cells.
During the proces of cytokinesis, the cell membrane pinches in at the cell equator, which forming the cleft called the cleavage furrow. The position which depends on the position of the astral and interpolar microtubules during the anaphase.During the process of anaphase, each pair of chromosomes is separated into two identical, and independent chromosomes.
The chromosomes which are separated by a structure that is known as the mitotic spindle.The cohesion proteins located between the sister chromatids disappear and the sister chromatids which located at the equator of the metaphase plate Anaphase where is starts,and separate and begin their migration toward the opposite poles of the mitotic spindle.
