Direct Observation of Hierarchical Folding in Single Riboswitch Aptamers

Riboswitches regulate genes through structural changes in ligand-binding RNA aptamers. Using an optical-trapping assay based on in situ transcription by a molecule of RNA polymerase, single nascent RNAs containing pbuE adenine riboswitch aptamers were unfolded and refolded. Multiple folding states w...
