Critical Torque for Kink Formation in Double-Stranded DNA
We measure the bending energy of double-stranded DNA in the nonlinear (sharply bent) regime. The measurements are obtained from the melting curves of stressed DNA ring molecules. The nonlinear elastic behavior is captured by a single parameter: the critical torque τ_{c} at which the molecule develop...
