Question 25: If apoptosis did not occur, DNA damage could lead to the propagation of mutations, potentially resulting in uncontrolled cell division and cancer. Question 23: According to Model 3, UV light is affecting a cell in the G1 phase. Question 24: Damage during the synthesis phase could result in incorrect DNA replication, leading to mutations and genomic instability. Question 26: Entering G0 allows damaged cells to exit the cell cycle, preventing the propagation of mutations and giving the cell time to repair damage. Question 27: If damaged cells do not die, they could accumulate mutations over several cycles, potentially leading to tumorigenesis and cancer.
