Frayed wires: a thermally stable form of DNA with two distinct structural domains.


In aqueous solutions containing mono- and divalent cations, the oligodeoxyribonucleotide d(A15G15) readily self-assembles into high-molecular weight species that resolve as discrete bands on native and denaturing electrophoresis gels. The complexes consist of an integer number of strands of d(A15G15), the number of strands range from one (the monomer) to… (More)
