Detailed explanation-1: -The G0 phase is a form of the resting state, or quiescence, in which cells reside until they receive appropriate signals-for example, from growth factors-stimulating them to re-enter and progress through the cell cycle.

Detailed explanation-2: -The interphase is also called as the resting phase. 90% of cell cycle is formed by interphase. Interphase is the phase of the cell cycle in which the cell spends and performs the majority of its time.

Detailed explanation-3: -The G0 phase is the phase in the cell cycle in which the cell is neither dividing nor preparing for division; hence it’s in a resting phase. The cell enters this phase after it is done dividing or duplicating (mitosis).

Detailed explanation-4: -Some cells enter G0 temporarily until an external signal triggers the onset of G1. Other cells that never or rarely divide, such as mature cardiac muscle and nerve cells, remain in G0 permanently.
