Practice question
Question
Cell cycle controller is robust and adaptable. Additionally, it functions like a switch to ensure unidirectional cell cycle. This switch like behavior can be achieved by which one of the following mechanisms
Explanation
The principle of cellular compartmentalization and cell cycle explains that SNARE-mediated trafficking, Hayflick limit, P53 and cyclin regulation control proliferation. Hence Positive feedback loops to regulate the activity of cyclin-dependent kinases fits best because it aligns with membrane trafficking and cell cycle control, as documented in authoritative sources on cell
