title: [On the possibility of bipolaronic states in DNA].
abstract: The possibility of the occurrence of bipolaronic states in homogeneous polynucleotide chains has been considered on the basis of the Holstein-Hubbard model. A phase diagram of the stability of bipolaronic states has been calculated for these chains. It was shown that, with the parameters characteristic for DNA, DNA can exhibit superconductivity with a transition temperature Tc approximately 6 K. The results obtained can serve as the basis for explaining the experiments with DNA superconductivity.
