Figure 3.

Force vs ΔL plots (left), unfolding force histograms (middle), and ΔL histograms (right) of the unfolding features when the two DNA strands in the internal loops have different poly(dA) sequences. (A) Two random sequences. (B) One (dA)21 and one random sequence. (C) Two (dA)10 sequences. (D) One (dA)10 and one random sequence. Solid curves are Gaussian fittings. N represents the number of molecules from which the FX curves were collected, and n represents the total number of unfolding features measured. All experiments were performed in presence of 5 nm AuNP.
