Fig. 1From: SL1 revisited: functional analysis of the structure and conformation of HIV-1 genome RNASecondary structural models of SL1. a Dissection of SL1 applied for this report. b Two models of SL1 predicted by Mfold program. The nucleotides at the bubble region substituted in the mutants are numbered. Five single substitution mutants and three double substitution mutants were constructedBack to article page
