Cytokinesis is the process of dividing the cell's cytoplasm, which requires the coordinated action of actin and myosin proteins. A mutation in the gene that encodes actin could disrupt the process of cytokinesis by altering the cell's ability to form the contractile ring necessary for the separation of daughter cells. Mutations in the other choices may affect other stages of the cell cycle but are less likely to directly impact cytokinesis.
