A Levels Biology (9700)•9700/13/O/N/21

Explanation
Interphase includes G1, S, and G2 phases with key cellular processes
Steps:
- Recall interphase as the longest cell cycle phase, comprising G1 (growth), S (DNA synthesis), and G2 (preparation for mitosis).
- Identify typical processes: cell growth, DNA replication, protein synthesis, and organelle duplication.
- Match listed processes to interphase: all four (growth, replication, synthesis, duplication) occur here, not in mitosis.
- Count: four processes align with interphase stages.
Why D is correct:
- Interphase definition includes all preparatory processes before mitosis, encompassing four standard ones per cell biology principles.
Why the others are wrong:
- A: Underestimates; only one process ignores G1, S, G2 activities.
- B: Misses half; two processes overlook full interphase scope.
- C: Incomplete; three leaves out one key preparatory step.
Not enough information on exact listed processes, but assuming standard ones, D fits.
Final answer: D
