Which of the following is false about cyclin-cdk complexes? Cdk's do not have to bind to cyclin proteins for complex to be active. OCdk/cyclin complexes phosphorylates proteins required to trigger next cell cycle phase. Process acts as molecular brakes to ensure cell is ready to continue with cell cycle. OCyclin concentrations increase gradually, but cdk must be phosphorylated by specific kinase for complex to be active |0|0
