What is the role of cyclins in a cell?​
svetoff [14.1K]

Answer:

Control of cell transition from one phase of the cell cycle to another

Explanation:

Control of cell transition from one phase of the cell cycle to another is not the only role of cyclin in the cell.

The role of cyclin C and H in the processes of transcription regulation is shown.

Cyclin H, together with the transcription factor TFIIH, plays a role in the phosphorylation of the CTD-tail of RNA polymerase II during the transcription process.

Cyclin L participates in the processes of primary transcript processing.
