title: [Selective effect of ligands on AT- and GC-pairs of DNA bases].
abstract: A method is proposed for investigating the specific influence of ligands on DNA AT- and GC-pairs based on the comparison of the width of transition temperature interval of DNA with a strongly pronounced block-structure and dependence of the control DNA melting temperature on their GC-content. Such a comparison allows to define separately the contribution of nonspecific effects causing a change of the width of transition temperature interval. The method is used for studying the specific influence of beta-alanine and nu-aminobutyric acid on AT- and GC-pairs.
