hpol η elongates an RNA primer opposite CPD or 8-oxodG.
A and C, hpol η (1.2 μm) elongated an RNA primer opposite CPD (A) or 8-oxodG (C) (5 μm) in the presence of a mixture of dNTPs or rNTPs (1 mm concentration of each nucleotide) for 5, 30, 55, and 240 min. B and D, hpol η (500 nm) was incubated with RNA/DNA (CPD) (B) and RNA/DNA (8-oxodG) (D) (5 μm) in the presence of 1 mm concentrations of each single dNTP or rNTP for 5, 30, and 55 min.
