1. G0 phase

   The G0 phase describes a cellular state outside of the replicative cell cycle. Classically, cells were thought to enter G0 primarily due to environmental factors, like nutrient deprivation, that limited the resources necessary for proliferation. Thus it was thought of as a resting phase. G0 is now known to take different forms and occur for multiple reasons. For example, most adult neuronal cells, among the most metabolically active cells in the body, are fully differentiated and reside in a terminal G0 phase. Neurons reside in this state, not because of stochastic or limited nutrient supply, but as a part of their developmental program. G0 was first suggested as a cell state based on early cell cycle studies. When the first studies defined the four phases of the cell cycle using radioactive labeling techniques, it was discovered that not all cells in a population proliferate at similar rates. A population's “growth fraction” – or the fraction of the population that was growing – was actively proliferating, but other cells existed in a non-proliferative state. Some of these non-proliferating cells could respond to extrinsic stimuli and proliferate by re-entering the cell cycle. Early contrasting views either considered non-proliferating cells to simply be in an extended G1 phase or in a cell cycle phase distinct from G1 – termed G0. Subsequent research pointed to a restriction point (R-point) in G1 where cells can enter G0 before the R-point but are committed to mitosis after the R-point. These early studies provided evidence for the existence of a G0 state to which access is restricted. These cells that do not divide further exit G1 phase to enter an inactive stage called quiescent stage.

1. G0 phase

   The G0 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. Some types of cells, such as nerve and heart muscle cells, become quiescent when they reach maturity but continue to perform their main functions for the rest of the organism's life. Multinucleated muscle cells that do not undergo cytokinesis are also often considered to be in the G0 stage. On occasion, a distinction in terms is made between a G0 cell and a 'quiescent' cell, which will never enter the G1 phase, whereas other G0 cells may.

Examples of G0 phase in a Sentence

1. Peter Attard Montalto:

   The fact the manifesto specifically links the monetary policy committee's actions to the 'second phase of transition' is an explicit benchmarking of monetary policy against political aims, it sets the SARB up for criticism in future as counter-revolutionaries and can further fuel the nationalisation debate.

2. Essence Securities analyst Jiang Ming:

   The (express delivery) industry has entered a phase of reorganization and upgrading, right now the firms aren't very different in terms of service standards. So if one wants to make upgrades, differentiate themselves, this will require large investments.

3. Chicago Teachers Union:

   We are disappointed the way this has gone, it’s been a frustrating process ... we are at the phase of negotiations where we have some really hard issues left.

4. Thierry Breton:

   Europe is the world's top industrial continent. The United States have lost much of their industrial know-how in the last phase of globalisation. They have to gradually rebuild it. China has added-value handicaps it is correcting, but the bulk of the industrial value chain, from large groups to SMEs, is based in Europe today. That's why all eyes are on Europe right now.

5. Lindsey Graham:

   The president of the United States has concluded that the War on Terror has reached a point that we can safely release people from Gitmo, the best I can say about him is he's unfocused. That's delusional thinking. The War on Terror has reached a lethal phase, and it is insane to be letting these people out of Gitmo to go back to the fight.
