Question

q 7. 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 phased of the cell cycle do these dna - copying errors most likely occur? m phase g2 phase g1 phase s phase

Explanation:

The cell cycle consists of different phases. The S phase (synthesis phase) is when DNA replication occurs. During DNA replication (which happens in the S phase), DNA - copying errors can take place. In the G₁ phase, the cell grows and prepares for DNA replication. In the G₂ phase, the cell prepares for mitosis. In the M phase, cell division (mitosis and cytokinesis) occurs. Since DNA - copying (replication) is the process where errors in DNA copying can occur and replication is in the S phase.

Answer:

S phase
