Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The mechanisms that control cellular division during the cell cycle normally are turned ____
A
on
B
off
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The central components of the cell-cycle control system are cyclin-dependent protein kinases (Cdks), whose activity depends on association with regulatory subunits called cyclins. Oscillations in the activities of various cyclin-Cdk complexes leads to the initiation of various cell-cycle events.

Detailed explanation-2: -G0 phase: The G0 phase is a resting phase where the cell has left the cycle and has stopped dividing. Non-dividing cells in multicellular eukaryotic organisms enter G0 from G1.

Detailed explanation-3: -In the absence of sugar, TORC1s assemble into a tubular structure, rendering them inactive and thus cell growth stops. TORC1 is an enzyme complex that controls the normal growth of our cells; but, when too active, it can promote diseases such as cancer.
