Abstract

Intramolecular folding in three tandem guanine repeats of human telomeric DNA has been investigated using optical-tweezers, MD simulation and circular dichroism. A mechanically and thermodynamically stable species in this sequence shows a structure consistent with a triplex conformation. A similar species has also been observed to coexist with a G-quadruplex in a DNA sequence with four tandem guanine repeats. This journal is © The Royal Society of Chemistry 2012
