Question

Quizplus · Accepted Answer

Cleavage furrow formation and cytokinesis are directly dependent on the polymerization of actin microfilaments. Cytochalasin B, by blocking this process, would disrupt the cell's ability to undergo cytokinesis, which is the final step of cell division where the cell splits into two daughter cells.
