Abstract

The thermodynamics of the DNA helix‐coil transition is studied, starting from the thermodynamical potential difference between the states helix and coil; this potential difference is understood as the difference in free energies. With only three parameters obtained from experimental data different quantities of the T~2~ phage DNA molecule are calculated. It is observed that the phase transition is of second order.

A simplified model for the closed circular DNA (ccDNA) is proposed to describe some specific features of the helix-coil transition in such molecules. The Hamiltonian of ccDNA is related to the one introduced earlier for the open chain DNA (ocDNA). The basic assumption is that the reduced energy of t
