Stretched and overwound DNA forms a Pauling-like structure with exposed bases
We investigate structural transitions within a single stretched and supercoiled DNA molecule. With negative supercoiling, for a stretching force >0.3 pN, we observe the coexistence of B-DNA and denatured DNA from σ ≈ −0.015 down to σ = −1. Surprisingly, for positively supercoiled DNA (σ > +0.0...
