Description: Supplemental Video 9: Composite video depicting the experimental procedure used to visualize DNA pairing on single λ DNA-dumbbell molecules by optical trapping. nA DNA pairing reaction (2 min) was performed with the 430 nt substrate at a 2 μm bead distance. Text and illustrations were inserted at appropriate places to facilitate description. A four-channel flow cell with a flow-free reservoir was used. Solution flow is top to bottom. First, two 1-μm streptavidin-coated polystyrene beads are c
