WebSep 9, 2024 · The G1 checkpoint is located at the end of G1 phase, before the transition to S phase. 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. Table of Contents show. WebAll of the cell's energy is focused on the complex and orderly division into two similar daughter cells.
