which following of the aspects of the cell cycle would be most disrupted by cytochalasin B
SPINDLE FORMATION
CLEVAGE FURROW
CELL ELONGATION
DNA SYNTHESIS
SPINDLE ATTACHMENT
To determine which aspect of the cell cycle would be most disrupted by cytochalasin B, we need to understand its mechanism of action. Cytochalasin B is a drug that inhibits actin filament formation, which is a crucial component of the cytoskeleton involved in various cellular processes.
Among the aspects of the cell cycle mentioned, the one most likely to be disrupted by cytochalasin B is CLEVAGE FURROW. The cleavage furrow is a structure that forms during cell division, specifically during cytokinesis, which is the process that divides the cytoplasm and separates the two daughter cells. The formation of the cleavage furrow relies heavily on actin filaments, which generate a contractile ring mechanism responsible for the constriction of the cell membrane.
By inhibiting actin filament formation, cytochalasin B interferes with the proper formation and function of the contractile ring, ultimately disrupting the formation of the cleavage furrow. This impairment would prevent the successful completion of cytokinesis, leading to the formation of multinucleated or abnormally shaped cells.
To recap, cytochalasin B is most likely to disrupt CLEVAGE FURROW formation during the cell cycle.
