Figure 3. Autoradiogram of steady-state DNA synthesis by WT and mutant HIV-1 RT in the presence of AZT-TP and 3 mM ATP.
A) Complete autoradiogram indicating primer, final product, and AZT-MP chain-termination sites. Experiments were carried out as described in the Materials and Methods. The time points for the reactions were 15, 30, 60, 90 and 120 min.
B) Different contrast of the final product bands from the autoradiogram presented in (A). This figure highlights that the addition of N348I to K70R/Y181C HIV-1 RT compensates for the antagonism of K70R by Y181C.
