GeneralClass 12AllAnswered 27 Mar 2026
Answer
Solution:G₁ phase (Gap 1 phase)
Explanation: During the G₁ phase, the cell exhibits:
- Active transcription of RNA
- Protein synthesis (enzymes, histones)
- Organelle replication (mitochondria, ribosomes)
- Cell growth in preparation for S phase
This phase accounts for the majority of interphase duration (typically 8-10 hours in human cells).
