Answer: Reformation of nuclear envelope.
- A Chromosome condensation into visible threads
- B Chromosome alignment at the cell equator
- C Reformation of nuclear envelope
- D Spindle fiber formation from centrosomes
Correct answer: C. Reformation of nuclear envelope
Explanation: Telophase: nuclear envelope reforms around chromosomes at each pole; chromosomes begin to decondense.
The cell cycle: G1 (growth and preparation), S (DNA replication, chromosome number stays 2n but DNA content doubles), G2 (final checks before division), and M (mitosis itself) - together, G1+S+G2 make up interphase.
Concept context
Mitosis and meiosis: how cells divide for growth, repair, and reproduction.
