The G0 phase (G zero) is a period in the cell cycle where cells exist in a quiescent state. Cells enter the G0 phase from a G1 phase checkpoint, such as the restriction point (animal cells) or the start point (yeast) usually in response to a lack of growth factors or nutrients. During the G0 phase, the cell-cycle machinery is dismantled and cyclins and cyclin-dependent kinases disappear. Some cells remain in the G0 phase until there is a reason for them to divide. ...
