Final answer:

a) Cyclins appear in some stages of the cell cycle and are degraded at other stages.

Step-by-step explanation:

Cyclins appear in some stages of the cell cycle and are degraded at other stages. They are a class of proteins that regulate the progression of the cell cycle by interacting with cyclin-dependent kinases (Cdks). The concentration of cyclin proteins fluctuates throughout the cell cycle, increasing in the previous stage and then being degraded after the cell moves to the next stage.
