摘要:
The present invention provides double stranded compositions that have a region that is complementary to a target nucleic acid. One of the targeting strand or the second strand comprises linked ribofuranosyl nucleosides and the other strand comprises linked modified nucleosides that have 3′-endo conformational geometry. The strands can be linked together or separate and may contain additional groups. The present invention also provides methods of using the compositions for modulating gene expression.
