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.
The alveoli are surrounded by tiny blood vessels, called capillaries carrying blood to and from the heart.
The answer is A.
You can remember this by thinking that since there was no change in the amino acid sequence, the mutation is silent in the fact that it didn't cause any trouble in the amino acid sequence.
