Figure 3.
Sequences employed in the experimental and modeling studies in T7 RNAP and yRNAPII complexes. The insertion position i + 1 occupied by the template nucleotide to be transcribed, G or O6-meG is shown in cyan. The pre-insertion position i + 2 occupied by the next to be transcribed nucleotide is in grey. The ribonucleotide previously incorporated at the 3′-end of the RNA is designated R1 and shown in green. The rNTP to be inserted opposite the lesion is called Incomer and colored red and the non-template DNA strand is colored in purple.
