Site-specific modification of RNA by functionality-transfer ODN probes.

Abstract

Efficient methods for the modification of RNA molecules have been expected as innovative biological tools and therapeutic methods. In this study, the development of a general method for site-specific RNA modification by the functionality-transfer ODN probes has been investigated. Site-specific and cytosine-selective RNA modifications were achieved by the functionality-transfer reaction. It was shown that the base and site-selectivity were due to the close proximity of the reactants in the DNA-RNA duplexes.
