WebCytokinesis. Although it is in fact one of the steps in the cell cycle, cytokinesis (pronounced SĪ-tō-kə-NEE-səs) is not one of the phases of mitosis or meiosis. It is the division of the cytoplasm (as opposed to karyokinesis, which is division of the nucleus ). It begins as the cell starts to lengthen during anaphase, and ends when the ...
