Abrupt Buckling Transition Observed during the Plectoneme Formation of Individual DNA Molecules
The response of single DNA molecules to externally applied forces and torques was directly measured using an angular optical trap. Upon overwinding, DNA buckled abruptly as revealed by a sharp extension drop followed by a torque plateau. When the DNA was held at the buckling transition, its extensio...
