Answer: Polyploid cells (multiple sets of chromosomes).
- A Two genetically normal, diploid daughter cells
- B Polyploid cells (multiple sets of chromosomes)
- C Complete absence of any cell division event
- D Only repair of damaged DNA without division
Correct answer: B. Polyploid cells (multiple sets of chromosomes)
Explanation: Endoreduplication: DNA replicates without cell division, producing polyploid cells. Common in plant cells and some animal tissues.
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.
