Single-Molecule FRET Assay for Studying Cotranscriptional RNA Folding

Cotranscriptional RNA folding plays important roles in gene regulation steps such as splicing, transcription termination, and translation initiation. Progression of our understanding of cotranscriptional RNA folding mechanisms is still retarded by the lacking of experimental tools to study the kinetics of cotranscriptional RNA folding properly. In this chapter, we describe fluorescence resonance energy transfer (FRET) assay that enables the study of RNA cotranscriptional folding at the single-molecule level.
