Phys. Rev. Lett. 98, 098101 (2007) [4 pages]Randomly Forced DNAReceived 19 July 2006; published 26 February 2007 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. © 2007 The American Physical Society URL:
