Abstract

We combined molecular tagging with microfluidics to study kinematics in a single DNA molecular digestion. Moving tags of both DNA ends revealed initial breakup of a single DNA molecule into fragments induced by limited enzymatic digestion and subsequent rapid formation of transient structure in encounter complex. The method enables us to analyze rapid dissociation of weakly bound complexes derived from intramolecular transfer.
