What are functions of the cell cycle checkpoints and when do they happen? What must be present in the environment outside of a cell in order for that cell to complete G1? What is the relationship between growth factors in an extracellular environment and G1?
Added by Veronica G.
Step 1
Cell cycle checkpoints are control mechanisms that ensure the proper progression of the cell cycle and prevent errors such as DNA damage or incomplete replication. There are three main checkpoints: G1 checkpoint, G2 checkpoint, and M checkpoint (also known as the Show more…
