About the Cover:
Using optical tweezers, three DNA constructs with varying numbers of nicks are “overstretched”, a mechanical transition where DNA’s extension suddenly increases by 70%. All three DNAs, including the topologically closed but rotationally unconstrained DNA, overstretch at ~65 pN (white curve). The main effect of nicks is seen upon retraction (blue curve).
