WebOct 4, 2024 · In most animals, cytokinesis begins sometime in late anaphase or early telophase, to ensure the chromosomes have been completely segregated. The … WebIn animals, cell division occurs when a band of cytoskeletal fibers called the contractile ring contracts inward and pinches the cell in two, a process called contractile cytokinesis. The indentation produced as the ring contracts inward is called the cleavage furrow. Animal cells can be pinched in two because they’re relatively soft and squishy.

WebIn animal cells, cytokinesis involves the formation of a contractile actomyosin ring (CR) that sits at the base of the ingressing equatorial furrow. Constriction of the CR drives continuous membrane furrowing until only a narrow cytoplasmic bridge separates the two cells. WebIn this article (which is part of the Cytokinesis series), we discuss recent studies that have begun to clarify both the spatial and the temporal order of ring assembly and that have illuminated the signals that trigger ring contraction in yeast. These studies add to the growing knowledge of the processes that control eukaryotic cell division.

WebIn animals, cytokinesis is centripetal. In animal cells, cytokinesis is accomplished by furrow formation which starts from the cell membrane. In this process cleavage of cytoplasm takes place. Thus, in animal cells, cytokinesis starts from the periphery and moves towards the centre, i.e., centripetal. So, the correct answer is ' Centripetal'.
