Abstract

The globular state of a randomly branched disordered heteropolymer-the simplest model of RNA with given secondary structure-is investigated using the replica approach in the mean-field approximation. It is shown that for dimensions of space less than four there is replica-symmetry breaking with power behaviour of the Parisi order parameter. The scale of fluctuations of links decreases when heterogeneity of interaction in the molecule increases.
