How many times does transcription occur during each round of the cell cycle?

Transcription occurs multiple times during each round of the cell cycle, particularly during the interphase stages (G1, S, and G2). In these phases, genes are transcribed as needed for cell growth, DNA replication, and preparation for mitosis. During mitosis (M phase), transcription is largely halted as the cell focuses on chromosome segregation. Overall, the frequency of transcription events varies depending on the specific needs of the cell at different points in the cycle.
