Of particular significance to the cell cycle, most microtubules – proteins that are required during mitosis – are produced during G 2. G0 phase. Not all cells are continually replicated. Non-replicating cells are found in a stage of the cell cycle called G 0. These cells may be quiescent (dormant) or senescent (aging or deteriorating).
