Long (dA)n.(dT)n tracts can form intramolecular triplexes under superhelical stress.
Plasmids containing long tracts of (dA)n.(dT)n have been prepared and their conformations examined in linear and supercoiled DNA using a series of chemical and enzymic probes which are known to be sensitive to unusual DNA structures. Under superhelical stress and in the presence of magnesium the seq...
