A Three-State Model with Loop Entropy for the Overstretching Transition of DNA

We introduce a three-state model for a single DNA chain under tension that distinguishes among B-DNA, S-DNA, and M (molten or denatured) segments and at the same time correctly accounts for the entropy of molten loops, characterized by the exponent c in the asymptotic expression S ∼ –c ln n for the...
