Research Abstract

Intelligent nucleic acids that can release/capture particular drug depending on the condition were created by designing and modifying drug-binding aptamers. Moreover, modified nucleotides were enzymatically incorporated to them by the post-modification method. The incorporation efficiencies were varied significantly depending on sequences around 3'-end of oligonucleotides tethered and chemical structures of modified nucleotides incorporated, which could be improved to some extent, by use of genetically modified polymerases.
