What is the primary result of cytokinesis?

• A. A single enlarged cell
• B. Two genetically identical daughter cells
• C. Detachment of the nucleus without cytoplasm division
• D. Fusion of two cells

Answer: (B)

Cytokinesis completes cell division by splitting the cytoplasm and the cell membrane, so the cell physically divides into two separate cells. After the nucleus has divided its chromosomes during mitosis, cytokinesis ensures each new cell gets its own share of cytoplasm and organelles. That final separation yields two genetically identical daughter cells because each inherits an exact copy of the parent’s chromosomes.

If cytokinesis didn’t happen, you’d end up with one cell that has two nuclei or a single enlarged cell, not two separate cells. The option describing detachment of the nucleus without cytoplasm division would leave the nucleus separated without forming two complete cells, and the idea of two cells fusing into one is the opposite of division. The two daughter cells outcome is the correct result.
