Elasticity of strongly stretched ssDNA
Copyright policy )Elasticity of strongly stretched ssDNA
We present a simple model which describes elastic response of single-stranded DNA (ssDNA) to stretching, including the regime of very high force (up to 1000 pN). ssDNA is modelled as a discreet persistent chain, whose ground state is a zigzag rather than a straight line configuration. This mimics the underlying molecular architecture and helps to explain the experimentally observed staturation of the stretching curve at very high force.
