Question

during metaphase, a stage in the cell cycle, a cell
o a. moves its chromosomes to opposite poles of the cell.
o b. stimulates its chromatin to condense into a chromosome.
o c. forms two new nuclear envelopes for chromosomes.
o d. aligns its chromosomes in the middle of the cell.

Explanation:

• In metaphase of the cell cycle, chromosomes line up at the metaphase plate (middle of the cell).
• Option A: Chromosomes move to opposite poles in anaphase.
• Option B: Chromatin condenses into chromosomes in prophase.
• Option C: New nuclear envelopes form in telophase.

Answer:

D. aligns its chromosomes in the middle of the cell.
