Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the nondividing stage or resting stage of the cell cycle called?
A
G0 Stage
B
G1 Stage
C
G2 Stage
D
G3 Stage
Explanation: 

Detailed explanation-1: -Within the G0 phase, a cell is regarded as being quiescent, in a non-dividing state.

Detailed explanation-2: -• G0 phase: resting state, or gap phase. Many cells spend most of their time in this phase either at rest or performing assigned duties. Generally resistant to chemotherapy.

Detailed explanation-3: -The G0 phase describes a cellular state outside of the replicative cell cycle. Classically, cells were thought to enter G0 primarily due to environmental factors, like nutrient deprivation, that limited the resources necessary for proliferation. Thus it was thought of as a resting phase.

Detailed explanation-4: -In the G0 phase, there is no cell division. It is the resting phase of the cell cycle. Cells in the G0 phase exit the cell cycle and re-enter after receiving signals.

Detailed explanation-5: -These cells that do not divide further exist G1 phase to enter an inactive stage called quiescent stage (G0) of the cell cycle. Cells in this stage remain metabolically active but no longer proliferate unless called on to do so depending on the requirement of the organism.
