Figure 7: The effect of the position of the c3A and 3-m-c3A lesions within the A4 tract on the insertion by T7 Sequenase opposite the modification using 10 or 100  𝜇 M of the dNTPs. The location of the modification is denoted by the numbering system in Scheme 1. The primers (Table 1, P23, P24, P25 and P26) stop 1 nt before the position of the c3A or 3-m-c3A modification.
