An ethidium-induced double helix of poly(dA)-poly(rU).

RESUMO
Equilibrium dialysis, relaxation kinetic, melting, and continuous variation mixing experiments on complexes of poly(dA) and poly(rU) demonstrate that ethidium induces conversion of a 1:1 mixture of these homopolymers (at one molar salt and 19 degrees C) from a three stranded to a two stranded helix. This is the first demonstration of a double helix of poly(dA)-poly(rU) in solution.
