WebMar 14, 2024 · Cell cycle checkpoints 1. G1 Checkpoint. The G1 checkpoint is the first checkpoint in the cell cycle of a mammalian cell and the start point in the yeast cell that determines whether the cell enters the cell cycle or not. The checkpoint is present between the G1 phase and S phase and is responsible for the entry of the cell in the … WebAs the cell continues through G1, it can either delay G1, enter G0, or proceed past the restriction point. DNA damage is the main indication for a cell to “restrict” and not enter the cell cycle. At the G1 checkpoint, a …
