Abstract
A replica trick similar to that used in spin glass theory is implemented to study a structure of large heteropolymeric globule or a heteropolymeric melt with random quenched sequence of monomers of two types (A and B). It is shown that a microphase separation third order phase transition occurs when the system of torn A and B links becomes thermodynamically incompatible. A periodic structure of A- and B-rich domains is formed, and the symmetry of this phase depends on the fraction of A and B monomers. When this fraction is 0.5 the lamellar structure is favoredKeywords
