Abstract:
An oligodeoxyribonucleotide (ODN) containing three C5-substituted arabinofuranosyluracils was synthesized by the post-synthetic modification method from the ODN containing three C5-substituted 2,2'-anhydrouridines. The stability of the modified ODN/DNA duplex was lower than that of the corresponding normal duplex but that of the modified ODN/RNA duplex showed little change. The modified ODN could induce RNase H activity and was resistant against nuclease.

RNA Structure
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
