WebStudy with Quizlet and memorize flashcards containing terms like Cells experience distinct cycles of activities, such as growth and division. These activities are summarized in the image below. Beginning in the G1 phase, proteins called cyclins begin to accumulate in the cell. Cyclins combine with certain molecules to form cyclin-dependent kinase complexes … WebCyclins help activate Cdks by phosphorylating them. The cell-cycle control system governs the cell-cycle machinery by cyclically activating and then inactivating the key proteins and protein complexes that initiate or regulate DNA replication, mitosis, and cytokinesis. Cyclin expression is a key regulator of this process.
