  • Title: Unfolding single RNA molecules by mechanical force: a stochastic kinetic method.
    Author: Liu F, Ou-Yang ZC.
    Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2004 Oct; 70(4 Pt 1):040901. PubMed ID: 15600390.
    Abstract:
    Using simple polymer elastic theory and known RNA free energies, we study the single RNA folding and unfolding on the secondary structure level under mechanical constant force by stochastic kinetic simulation. As a primary application, this method is used to simulate the experiment performed by Science 292, 733 (2001)]. The extension-force curves in equilibrium and kinetic reaction rate constants for folding and unfolding are calculated. Our results show that the agreement between simulation and experimental measurements is satisfactory.
