The steady state in the kinetic pathways of the long single-strand RNA (ssRNA) in the approximation of a coarse-grained model is studied with analytic calculations. It is assumed that the characteristic time of the secondary-structure rearrangement is much longer than that for the formation of the tertiary structure. The entropy and the specific heat of the system as functions of the temperature are calculated and plotted. A non-equilibrium phase transition of the 2nd order has been observed. The possible biological implication of the obtained results is discussed.
