(d) Interactions between cyclins and cyclin-dependent kinases control the cell cycle. Explain how the presence or absence of inhibitors of cyclin-dependent kinases might play a role
BI VE

Inhibitors of cyclin-dependent kinases might play a role in regulating the concentration of cyclin in the cell cycle.

Explanation:

The presence of inhibitors of cyclin-dependent kinases has a great importance because it controls the concentration of cyclin that is necessary for the cell cycle. If inhibitors of cyclin-dependent kinases is absent , the amount of cyclin increases in the cell formation and cause  a great damage to the cell cycle and the cell which is produced is abnormal or other irregularities.
