if the cell is not to divide, at which checkpoint will the cycle stop and move into a resting phase?

G1 checkpoint

If cells don't pass the G1 checkpoint, they may "loop out" of the cell cycle and into a resting state called G0, from which they may subsequently re-enter G1 under the appropriate conditions.
