Give an account of `G_0` phase.

Explanation

Some cells exit `G_(1)` and enters a quiescent stage called `G_(0)`, where the cells remain metabolically active without proliferation. Cells and exist for long periods in `G_(0)` phase. In `G_(0)` cells cease growth with reduced rate of RNA and protein synthesis. The `G_(0)` Phase is not permanent. Mature neuron and skeletal muscle cell remain permanently in `G_(0)`. many cells in animal remains in `G_(0)` unless called onto proliferate by appropriate growth factors or other extracellular signals. `G_(0)` cells are not dormant.
