Modified oligonucleotides containing both A-form conformation geometry and B-from conformation geometry nucleotides are disclosed. The B-form geometry allows the oligonucleotide to serve as substrates for RNase H when bound to a target nucleic acid strand. The A-form geometry imparts properties to the oligonucleotide that modulate binding affinity and nuclease resistance. By utilizing C2′ endo sugars or O4′ endo sugars, the B-form characteristics are imparted to a portion of the oligonucleotide. The A-form characteristics are imparted via use of either 2′-O-modified nucleotides that have 3′ endo geometries or use of end caps having particular nuclease stability or by use of both of these in conjunction with each other.
