Step-by-step solution

The cell cycle is controlled by the enzymes like cyclin-dependent kinases (Cdks). The Cdks phosphorylate amino acids like serine and threonine which initiate or block activities related to cell cycle. In eukaryotes, multiple cyclins are present and each of which acts during a specific checkpoint in cell cycle regulation. Common classes of cyclins includes G1-phase cyclins G1/S-phase cyclins S-phase cyclins M-phase cyclins M-phase cyclins form M-CDK complexes and drive the cell's entry into mitosis and acts on the a
