Definition of Cytokinesis
Cytokinesis the is the last step in the process of cell division. In this step, the cytoplasm of the parental cell divides and results in the formation of two new daughter cells. Cytokinesis happens in both mitosis as well as in meiosis. Cytokinesis is responsible for separating the cell into two halves and it makes sure that each daughter cell has received one nucleus.
It gets initiated when the cell is in anaphase and progresses till telophase. Beneath the cell membrane, a proteinaceous ring is formed which has the ability to shrink and pinch the membrane inwards and resultantly gives rise to the cleavage furrow. This ring is termed a contractile ring and it keeps on shrinking to the point when the cells get separated.
