Parallel nucleic acid recognition by the LNA (locked nucleic acid) stereoisomers beta-L-LNA and alpha-D-LNA; studies in the mirror image world.

Two LNA (locked nucleic acid) stereoisomers (beta-L-LNA and alpha-D-LNA) are evaluated in the mirror-image world, that is by the study of two mixed sequences of LNA and alpha-L-LNA and their L-DNA and L-RNA complements. Both are found to display high-affinity RNA-recognition by the formation of duplexes with parallel strand orientation.
