Fe b 20 03 Poland - Scheraga models and the DNA denaturation transition
نویسنده
چکیده
Poland-Scheraga models were introduced to describe the DNA denaturation transition. We give a rigorous discussion of a family of these models. We derive possible scaling functions about the phase transition point and review common examples. We introduce exactly solvable directed examples, which fully account for excluded volume effects. In particular, we present a two-dimensional Poland-Scheraga model with a first order phase transition, as observed experimentally. This illuminates recent suggestions as to how the Poland-Scheraga class might be modified in order to display a first order transition.

Poland-Scheraga models and the DNA denaturation transition
Poland-Scheraga models were introduced to describe the DNA denaturation transition. We give a rigorous and refined discussion of a family of these models. We derive possible scaling functions in the neighborhood of the phase transition point and review common examples. We introduce a self-avoiding Poland-Scheraga model displaying a first order phase transition in two and three dimensions. We al...

متن کاملEffects of mechanical strain on thermal denaturation of DNA
A class of simple statistical mechanical models for DNA melting, first proposed by Poland and Scheraga, have been demonstrated to exhibit first or second order thermodynamic singularity, notwithstanding the intrinsic one-dimensional nature of the problem. In the present paper we show that the inclusion of twist elastic energy in the Poland-Scheraga models either leads to suppression of the ther...
متن کاملGeneralized Poland-Scheraga denaturation model and two-dimensional renewal processes
The Poland-Scheraga model describes the denaturation transition of two complementary – in particular, equally long – strands of DNA, and it has enjoyed a remarkable success both for quantitative modeling purposes and at a more theoretical level. The solvable character of the homogeneous version of the model is one of features to which its success is due. In the bio-physical literature a general...
متن کاملOn the role of mismatches in DNA denaturation
– In the framework of the Poland Scheraga model of DNA denaturation, we derive a recursion relation for the partition function of double stranded DNA, allowing for mismatches between the two strands. This relation is studied numerically using standard parameters for the stacking energies and loop entropies. For complementary strands (of length 1000), we find that mismatches are significant only...
