Abstract

Understanding the folding process of DNA origami is a critical steppingstone to the broader implementation of nucleic acid nanofabrication technology but is notably non-trivial. Origami are formed by several hundred cooperative hybridization events – folds – between spatially separate domains of a scaffold, derived from a viral genome, and oligomeric staples, each of which is difficult to detect independently. Here, we present a real-time probe of the unit operation of origami assembly, a single fold across the scaffold as a function of hybridization domain separation – fold distance – and staple:scaffold ratio. This novel approach to the folding problem elucidates a previously unobserved blocked state that acts as a limit on yield for single folds, and which may manifest as a barrier in whole origami assembly.
