Cyclins and cyclin-dependent kinases
What Cyclins and cyclin-dependent kinases means in Biology A-Level, as defined for OCR.
Definition of Cyclins and cyclin-dependent kinases
Check what you remember
Read the wording for your board, then hide it and explain Cyclins and cyclin-dependent kinases in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Proteins whose concentration varies cyclically bind to and activate cyclin-dependent kinases, and the active complexes phosphorylate target proteins that move the cycle forward.
