A period in the cell cycle in which cells exist in a quiescent state. GO phase is viewed as either an extended G1 phase. Which factors determine whether a cell enters G0? It depends on the organisms stage in development. It is the phase of the cell cycle during which a cell is neither dividing nor preparing to divide. During this period the cell performs regulatory and its basic cellular functions. The cell cycle typically refers to the process by which the cell can grow and repair itself.
