11. Members of this family are required for cytokinesis . 12. MDia1 is highly homologous to Drosophila diaphanous, regulating the cytokinetic ring during cytokinesis . 13. During mitotic progression, typically after the anaphase onset, the cell may undergo cytokinesis . 14. The processes of karyokinesis ( mitosis ) and cytokinesis work together to result in cleavage. 15. While mitosis can occur in the absence of cytokinesis , cytokinesis requires the mitotic apparatus. 16. While mitosis can occur in the absence of cytokinesis, cytokinesis requires the mitotic apparatus. 17. This enabled detailed, quantitative studies of the process of cell cleavage ( cytokinesis ). 18. The Aurora B kinase is a chromosome passenger protein and regulates chromosome segregation and cytokinesis . 19. IQGAP1 can crosslink actin, and in many organisms, IQGAP1 is involved in cytokinesis . 20. Formin-related proteins have been implicated in morphogenesis, cytokinesis , and cell polarity.
