Randomly forced DNA
arXiv:cond-mat/0607512 · doi:10.1103/PhysRevLett.98.098101
Abstract
We study the effect of random forces on a double stranded DNA in unzipping the two strands, analogous to the problem of an adsorbed polymer under a random force. The ground state develops bubbles of various lengths as the random force fluctuation is increased. The unzipping phase diagram is shown to be drastically different from the pure case.
