 We propose a dynamic transition, which has potential application in understanding non-equilibrium processes such as transcription and replication of DNA, unfolding of proteins and RNA etc. Here, we demonstrate that without changing the physiological condition, a DNA may be brought to a new dynamic state from the zipped or unzipped state by varying the frequency of the applied force. We report the value of various critical exponents associated with this transition, which are amenable to verification in the force spectroscopic experiments.
A simple model of DNA based on two interacting polymers has been used to study the unzipping of a double stranded DNA subjected to a periodic force. We propose a dynamical transition, where without changing the physiological condition, it is possible to bring DNA from the zipped /unzipped state to a new dynamic (hysteretic) state by varying the frequency of the applied force. Our studies reveal that the area of the hystersis loop grows with the same exponents as of the isotropic spin systems. These exponents are amenable to verification in the force spectroscopic experiments.
