Bulges are common structural motifs in RNA secondary structure and are thought to play important roles in RNA-protein and RNA-drug interactions. Adenosine bases are the most commonly occurring unpaired base in double helical RNA secondary structures. The solution conformation and dynamics of a 25-nucleotide RNA duplex containing an unpaired adenosine, r(GGCAGAGUGCCGC): r(GCGGCACCUGCC) have been studied by NMR spectroscopy and MORASS iterative relaxation matrix structural refinement ...
