cell cycle dependent fluctuations of o6-methylguanine dna transferase with an increasing enzyme activity in late g1 and a maximum in early s phase indicate that cells possess an increased potential for eliminating promutagenic o6-methylguanine during the most transformation sensitive parts of the cell cycle to prevent base-mispairing during dna replication or transcription .
