Question

which phase of mitosis is correctly matched to its definition?
during interphase, replicated chromosomes condense into visible structures.
during telophase, the nuclear membrane disassembles.
during prophase, each chromosome replicates.
during interphase, chromatids move to opposite ends of the cell.
during metaphase, replicated chromosomes align in the middle of the cell.

Explanation:

• Interphase: It is the phase where the cell prepares for mitosis. Chromosomes replicate during interphase, not condense (condensation occurs in prophase). Also, chromatids moving to opposite ends is not an interphase event.
• Telophase: The nuclear membrane reassembles in telophase, not disassembles (disassembly is in prophase).
• Prophase: Chromosome replication occurs in interphase, not prophase.
• Metaphase: During metaphase, replicated chromosomes (attached to spindle fibers) align in the middle (equatorial plane) of the cell.

Answer:

During metaphase, replicated chromosomes align in the middle of the cell.
