Question

what happens during anaphase? the cytoplasm divides, and the two daughter cells separate. a nuclear membrane forms around each set of dna. the sister chromatids separate and move to opposite sides of the cell. the chromosomes line up in the middle of the cell.

Explanation:

• Analyze each option:
• "The cytoplasm divides, and the two daughter cells separate" describes cytokinesis, not anaphase.
• "A nuclear membrane forms around each set of DNA" is telophase.
• "The chromosomes line up in the middle of the cell" is metaphase.
• "The sister chromatids separate and move to opposite sides of the cell" matches the events of anaphase (sister chromatids are pulled apart to opposite poles by spindle fibers).

Answer:

The sister chromatids separate and move to opposite sides of the cell.
