🧬 Cyclin & CDK in Cell Cycle | Complete Conceptual Lecture In this lecture, we explore Cyclins and Cyclin-Dependent Kinases (CDKs) in detail and understand how they control the progression of the eukaryotic cell cycle. 🔬 Topics Covered: What are Cyclins and CDKs? Structure and basic mechanism of Cyclin–CDK complexes Major Cyclins: Cyclin D, E, A and B Major CDKs: CDK4/6, CDK2 and CDK1 Formation and activation of Cyclin–CDK complexes Activating and inhibitory phosphorylation Role of CAK and Wee1 kinase Regulation by Cdc25 phosphatase Cyclin–CDK regulation at different cell-cycle stages G1 → S transition G2 → M transition Role of Cyclin B–CDK1 in M-phase entry Molecular mechanisms of cell-cycle regulation Important CSIR NET/GATE conceptual points 🎯 Useful for: CSIR NET Life Sciences • GATE • SET • TIFR • IIT JAM • M.Sc. Entrance & University Exams 📚 This lecture focuses on understanding the molecular mechanism behind cell-cycle progression, rather than simply memorizing Cyclin/CDK names.
