There and (Slowly) Back Again: Entropy-Driven Hysteresis in a Model of DNA Overstretching
When pulled along its axis, double-stranded DNA elongates abruptly at a force of ∼65 pN. Two physical pictures have been developed to describe this overstretched state. The first proposes that strong forces induce a phase transition to a molten state consisting of unhybridized single strands. The se...
