Question

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

Explanation:

• Telophase: Nuclear membrane reassembles, not disassembles.
• Interphase: Cell grows and replicates DNA; chromatids moving is during mitotic phases (not interphase). Chromosome condensation (visible structures) occurs in prophase (not interphase).
• Prophase: Chromosomes condense; DNA replication (chromosome replication) occurs in interphase.
• Metaphase: Replicated chromosomes (sister chromatids still attached at centromere) align at the cell's equatorial plane (middle of the cell).

Answer:

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