摘 要:THE intra- and intermolecular forces of DNA are essential to understanding its structure andfunctional behavior. However, direct measurement of interaction forces requires that the stateof a system be monitored simultaneously while an independent force is applied. Until now, on-ly X-ray crystallography, light scattering, and nuclear magnetic resonance spectroscopy havebeen used to measure these molecular forces using indirect physical and thermodynamic meth-
