DNA-copying errors most likely occur during the A. S phase of the cell cycle. The S phase (Synthesis phase) is when DNA replication occurs, and that's when the DNA is copied to prepare for cell division. Errors during this replication process can lead to mutations and potentially contribute to cancer development.
Scientists have reported that more than 95% of the factors that lead to some types of cancers are caused by random DNA-copying errors.
During which phase of the cell cycle do these DNA-copying errors most likely occur?
A.S phase
B.G1 phase
C.G2 phase
D.M phase
