A Levels Biology (9700)•9700/11/O/N/21
Explanation
Components of the Cell Cycle Steps:
- Recall the cell cycle includes interphase (G1, S, G2) and mitosis (prophase, metaphase, anaphase, telophase), plus cytokinesis.
- Identify events 1, 2, and 3 from the listed options (not provided here).
- Check each against standard cell cycle phases.
- Confirm all three match defined stages.
Not enough information: Events 1, 2, and 3 are not specified, preventing precise verification.
Why A is correct:
- Assumes all listed events align with cell cycle definition as growth, DNA replication, and division.
Why the others are wrong:
- B excludes 2 and 3, omitting key phases.
- C excludes 2, missing a core event.
- D excludes 1, ignoring an essential stage.
Final answer: A
Topic: Replication and division of nuclei and cells
