Bypass efficiencies (a) and mutagenic potentials (b) of N3-EtdT, O2-EtdT, O4-EtdT, N3-CMdT, and O4-CMdT during transcription in mammalian cellsthat are proficient or deficient in Alkbh2 or Alkbh3.The data represent the mean and standard error of the mean results from three independent experiments.‘*’, P< 0.05; ‘**’, P< 0.01. The P values were calculated by using unpaired two-tailed Student’s t-test.
