RNA Intramolecular Dynamics by Single‐Molecule FRET

Investigation of single RNA molecules using fluorescence resonance energy transfer (FRET) is a powerful approach to investigate dynamic and thermodynamic aspects of the folding process of a given RNA. Its application requires interdisciplinary work from the fields of chemistry, biochemistry, and physics. The present work gives detailed instructions on the synthesis of RNA molecules labeled with two fluorescent dyes interacting by FRET, as well as on their investigation by single-molecule fluorescence spectroscopy.
