Cyclin binding leads to a change in the _________________ of kinase.

A. pH

B. temperature

C. concentration

D. conformation

I got this question in an interview.

The doubt is from Cellular Reproduction in chapter DNA Replication and Repair, Cellular Reproduction of Cell Biology

Right answer is D. conformation

To explain I would say: Cyclin binding leads to a change in the conformation of catalytic subunit of kinase enzyme by binding to its catalytic site. This binding allows the cyclin dependent kinase (CDK) to phosphorylate its substrates.
