Answer:
CHK2, p53, p21, cell cycle progression.
Explanation:
In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.
