WebCytokinesis is the final step of mitosis whereby two daughter cells physically separate. It is initiated by the assembly of an actomyosin contractile ring at the mitotic cell equator, which constricts the cytoplasm between the two reforming nuclei resulting in the formation of a narrow intercellular bridge filled with central spindle microtubule bundles. WebSep 20, 2024 · Cytokinesis can simply be described as the point where the cell is essentially done replicating (copying) and moving things around and is ready to cleave in two.
