Force: a new structural control parameter?
Recent technical developments that allow precise force measurements on single molecules, together with numerical simulations of biomolecules under stress, offer new insight into how stress affects molecular interactions, and how large the force developed by a travelling enzyme such as RNA polymerase can be.
