Reseаrchers meаsured the rаte оf DNA synthesis in cells during different phases оf the cell cycle. They used radiоactive nucleotides to track DNA replication and measured incorporation rates over time. graph 3.jpg A mutation in DNA polymerase reduces its synthesis rate by 50%. At which time point would this mutation have the greatest impact on normal cell function?
