Detection of triple-helix related structures adopted by poly(dG)-poly(dC) sequences in supercoiled plasmid DNA.

Negative superhelical strain induces the poly(dG)-poly(dC) sequence to adopt two totally different types of triple-helices, either a dG.dG.dC triplex in the presence of Mg(+)+ at both neutral and acidic pHs or a protonated dC+.dG.dC triplex in the absence of Mg(+)+ ions at acidic pH (1). To examine...
