can someone explain the kinase cyclins? How do they act as checkpoints?
i asked a similar question. I’m pretty sure cyclin binds to cyclin dependent kinases which phosphorylates a target protein to proceed in the cell cycle if everything’s good in the cell. If not, another response occurs
Kinases are responsible for adding phosphate group to the second messenger to provide the energy to go to the target protein (as jazmine said) to get the response that is needed
