In animal cells, how do daughter cells physically split apart after mitosis during cytokinesis?

• A. Chromosomes are pulled to opposite poles by shortening of kinetochore microtubules, which directly divides the cytoplasm
• B. New nuclei form and then the nuclear envelope expands outward until it separates the cell into two compartments
• C. A contractile ring of actin and myosin II constricts at the cell equator to form a cleavage furrow that pinches the cell into two
• D. A cell plate forms from Golgi-derived vesicles fusing at the center of the cell, creating a new wall that splits the cell

Answer: (C)
