G0 is a non-dividing phase of the cell cycle where the cell is not preparing to replicate. Cells may enter G0 during G1 and rema
in for the rest of their life, or a signal may cause them to re-enter G1 and continue in the cell cycle. Consider two cells: a stomach-lining epithelial cell dividing more than twice a day and a liver cell dividing every year or two. Which cell is likely to be in G0 phase and why?
