Thirty-one RNA duplexes containing single-nucleotide bulge loops were optically melted in 1 M NaCl, and the thermodynamic parameters ΔH°, ΔS°, ΔG°(37), and T(M) for each sequence were determined. The bulge loops were of the group II variety, where the bulged nucleotide is identical to one of its nearest neighbors, leading to ambiguity as to the exact position of the bulge. The data were used to develop a model to predict the free energy of an RNA duplex containing a single-nucleotide bulge. The destabilization of the duplex by the bulge was primarily related to the stability of the stems adjacent to the bulge. Specifically, there was a direct correlation between the destabilization of the duplex and the stability of the less stable duplex stem. Since there is an ambiguity of the bulge position for group II bulges, several different stem combinations are possible. The destabilization of group II bulge loops is similar to the destabilization of group I bulge loops, if the second least stable stem is used to predict the influence of the group II bulge. In-line structure probing of the group II bulge loop embedded in a hairpin indicates that the bulged nucleotide is the one positioned farther from the hairpin loop.
