Question

At the G₁ stage, which phenomenon takes place?

• A. DNA synthesis
• B. RNA synthesis
• C. reverse transcription
• D. all of these

Answer 1

Answer: (B)

At the G₁ phase, the RNA and protein are synthesized. The G₁ phase is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part of the interphase, the cell synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis. G₁ phase ends when the cell moves into the S phase of interphase.
