Figure 6.

Gel analysis of primer extension products synthesized by (a) AMV-RT and (b) human DNA polymerase β, from template containing 8-nitro-2′-O-methylguanosine. The experimental details are as described in Figure 5. The tracks marked –E and –T correspond to control reactions carried out without the addition of enzyme and template, respectively. Band intensities are reported in the Supplementary Material.
