The cyclin dependent kinases (CDK) are crucial regulators in the cell division cycle. CDKs are catalytic proteins that phosphorylate other cell cyde proteins only when the appropiate cyclin is bound. Select one a. FALSE b. TRUE Clear my choice

b. TRUE<br /><br />Cyclin-dependent kinases (CDKs) are indeed crucial regulators in the cell division cycle. They are catalytic proteins that phosphorylate other cell cycle proteins, but they only become active and function when the appropriate cyclin is bound to them. This binding allows the CDK to phosphorylate target proteins, which in turn triggers various processes necessary for cell division to occur.
