Sequence and mfold-predicted secondary structure of TAR and Psi RNA constructs used in this study. a HIV-1 TARpolyA. b HIV-1 Psi. c SIVmac TAR. d SIVmac Psi. In all cases, numbering refers to the nt position in gRNA. The box in (a) indicates HIV-1 TAR RNA. The boxes in (b, d) indicate the ∆DIS mutation, where DIS loop residues are replaced with a GNRA-type tetraloop (GAGA) to eliminate dimerization
