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 5 phase 6 G_(1) phose (c) G, phase 6 M phase

The question is asking during which phase of the cell cycle do most DNA-copying errors occur that lead to some types of cancers. The cell cycle consists of several phases: G1 phase, S phase, G2 phase, and M phase. The S phase, or synthesis phase, is when DNA replication occurs. Therefore, if there are errors in DNA copying, they would most likely occur during the S phase.
