The correct Answer is:
To answer the question about what phenomenon takes place at the G1 stage of the cell cycle, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Cell Cycle**: The cell cycle consists of several phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). Each phase has specific activities and processes. 2. **Identifying the G1 Phase**: The G1 phase is the first stage of interphase, occurring after cell division. During this phase, the cell grows and prepares for DNA synthesis. 3. **Examining the Options**: - **DNA Synthesis**: This occurs during the S phase, not G1. Thus, this option is incorrect. - **RNA Transcription**: This process involves copying a segment of DNA into RNA. It occurs during the G1 phase as the cell prepares for the next stages of the cycle. Therefore, this option is correct. - **Reverse Transcription**: This is a process that synthesizes DNA from an RNA template, which does not occur during the G1 phase. Hence, this option is incorrect. - **All of These**: Since not all options are correct, this option is also incorrect. 4. **Conclusion**: The correct phenomenon that takes place during the G1 stage is RNA transcription. ### Final Answer: At the G1 stage, the phenomenon that takes place is **RNA transcription**. ---
