A theoretical perspective of the physical properties of different RNA modifications with respect to RNA duplexes

Abstract

Epitranscriptomic variations include >140 different RNA modifications, many of which can serve as disease biomarkers.Owing to the challenges on synthesizing modified RNA oligos, majority of earlier studies on the effects of RNA modifications to RNA duplexes focused on selected individual epitranscriptomic variation. There are also limited development on the computational modeling of RNA duplexes containing a specific epitranscriptomic variation.This study aims to theoretically estimate the physical properties of different modified ribonucleosides and compare their variations with respect to altering the molecular structure of an RNA duplex.
