We consider two models of interacting DNA molecules:First is(four parametric)bubble coalescence model in interacting DNAs(shortly:BCi-DNA).Second is(three parametric)bubble coalescence model in a condensed DNA molecules(shortly BCC-DNA).To study bubble coalescence thermodynamics of BCi-DNA and BCC-DNA models we use methods of statistical ***,we define Hamiltonian of each model and give their translation-invariant Gibbs measures(TiGMs).For the first model,we find parameters such that corresponding Hamiltonian has up to three TiGMs(three phases of system)biologically meaning existence of three states:“No bubble coalescence”,“Dominated soft zone”,“Bubble coalescence”.For the second model,we show that for any(admissible)parameters,this model has unique *** is a state where“No bubble coalescence”phasedominates.
