Stretching DNA 2.05 – Simulations of Stretching DNA

Stretching DNA 2.05

:: DESCRIPTION

Stretching DNA explores stretching just a single strand of DNA using optical tweezers or fluid flow. Experiment with the forces involved and measure the relationship between the stretched DNA length and the force required to keep it stretched. Is DNA more like a rope or like a spring?
