1.	Question : Give an account of G_0 phase.
Answer» Solution :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.
