Abstract
Compounds referred to herein as oligonucleotide clamps are provided that stably bind to target polynucleotides in a sequence-specific manner. The oligonucleotide clamps comprise one or more oligonucleotide moieties capable of specifically binding to a target polynucleotide and one or more pairs of binding moieties covalently linked to the oligonucleotide moieties. In accordance with the invention, upon annealing of the oligonucleotide moieties to the target polynucleotide, the binding moieties of a pair are brought into juxtaposition so that they form a stable covalent or non-covalent linkage or complex. The interaction of the binding moieties of the one or more pairs effectively clamps the specifically annealed oligonucleotide moieties to the target polynucleotide.
