Quantitative Parametrs of Cooperative Interactions of the Oligodeoxyribonucleotides on the Complementary Template

Abstract

The cooperative interactions of oligonucleotides on the complementary template were studied using the quantitative analysis of the template alkylation with the oligonucleotides bearing covalently attached 4-[N-(2-chloroethyl)-N-methylamino]benzyl group at 5′-end. The influence of the mismatched nucleotides and the stabilizing N-(2-hydroxyethyl)phenazinium group at the 5′- and 3′-ends of the oligonucleotides on the parameters of cooperativity was evaluated.
