Answer:
Basically, cyclins are named such because they undergo a constant cycle of synthesis and degradation during cell division. When cyclins are synthesized, they act as an activating protein and bind to Cdks forming a cyclin-Cdk complex. This complex then acts as a signal to the cell to pass to the next cell cycle phase.
Explanation:
Cyclins are the regulatory proteins, which control the progression of the cell cycle. Cyclin also plays a crucial role in cell division by binding with the cyclin-dependent kinases.
Mitosis is the process in which the parent cell copies the genetic material and delivers it to the daughter cells formed.
Cyclin in the cell cycle regulates the progression of the cell cycle by binding with Cdks. These complexes of different Cdks are formed, which play crucial roles in different stages of the cell cycle.
For instance, the cyclins from the D-type family regulate the activation of Cdks complexes and allow the cell to progress in the G1 phase of the cell cycle.
Thus, cyclins are the regulatory proteins that in the activated form of Cdks progress the cell cycle.
