WebApr 9, 2024 · When a cell is produced through fertilization or cell division, there is usually a lag before it undergoes DNA synthesis (replication). This lag period is called Gap 1 ( G1 ), and ends with the onset of the DNA synthesis ( S) phase, during which each chromosome is … WebThe general answer is that internal and external cues trigger signaling pathways inside the cell that activate, or inactivate, a set of core proteins that move the cell cycle forward. You can learn more about these proteins, and see examples of how they are affected by cues such as DNA damage, in the article on cell cycle regulators.
