What is the role of cyclin-dependent kinases in the cell cycle?

Question 5 options:

They stop the cycle if something has gone wrong.

They catalyze the condensation of the chromosomes.

They provide the energy for the actions of the spindle fibers.

They initiate various stages of the cell cycle.

The role of cyclin-dependent kinases in the cell cycle is that, they stop the cycle if something has gone wrong.

Explanation:

In Eukaryotic cells cyclin-dependent kinases are universal regulator cell. It undergoes a constant cycle and degradation known as Mitotic and G1 cyclin. When cycle dependent cycle synthesize it acts like an activating protein and then bind to cyclin-dependent kinases forming cyclin-dependent kinases complex.

Now it acts as signal to the cell to pass the next phase of cell cycle. After its cyclin gets degraded, it deactivates the cyclin-dependent kinases and from particular phase signalling stop
