Question

what happens during telophase? the chromosomes line up in the middle of the cell. the cytoplasm divides, and the two daughter cells separate. a nuclear membrane forms around each set of dna. the chromosomes condense, and the nuclear membrane disappears.

Explanation:

During telophase, which is the final stage of mitosis, the chromosomes have reached the opposite poles of the cell. A nuclear membrane begins to form around each set of DNA (chromosomes) at the two poles. This is part of the process of re - establishing the nucleus in each of the new daughter cells.

• Option A: The chromosomes line up in the middle of the cell during metaphase, not telophase.
• Option B: The cytoplasm divides, and the two daughter cells separate during cytokinesis (which often overlaps with telophase but is a distinct process).
• Option D: The chromosomes condense, and the nuclear membrane disappears during prophase.

Answer:

C. A nuclear membrane forms around each set of DNA.
