Answer 1

The G0 phase (referred to the G zero phase) or resting phase is a period in the cell cycle in which cells exist in a quiescent state. G0 phase is viewed as either an extended G1 phase, where the cell is neither dividing nor preparing to divide, or a distinct quiescent stage that occurs outside of the cell cycle.

Answer 2

⁕Final Answer⁕

Cell cycle includes 4 stages called G0, G1, synthesis and G2 stage. Among which G0 or also called quiescent stage, in this stage the cells are metabolically active, but don’t do proliferation until they are told to do so. In this stage no sign of division is seen , nor they are preparing to divide.

Explanation:

• G0 or  also called quiescent stage, is the stage of the cell cycle where, the cells present are metabolically active, but do not show any activity of proliferation until they are ordered to do so.

• Some examples of the cells which are present in this stage are heart and nerve cells which reaches maturity.

• G0 phase is also called extended G1 stage.

• Multinucleated muscle cells that do not undergo cytokines are also considered to be a part of this stage.
