[Selective effect of ionization of nitrogen bases on the thermostability of AT- and GC-pairs of DNA].
The ionization specific influence of nitrogen bases on thermostability of AT- and GC-pairs of DNA has been investigated by the method of DNAs melting temperature analysis. It has been shown that the change of temperature interval of DNA helix-coil transition when changing pH environment is due to specific ionization of AT- and GC-pairs of nitrogen bases.
