Figure 7. — Relative viscosity (η/η₀) dependence of poly(A)•poly(U)/coralyne (open triangle) and poly(A)•2poly(U)/coralyne (closed circle) systems on the C_D/C_P ratio. C_P = 1.6 × 10⁻⁴ M, C_D from 0 to 2.6 × 10 ^{− 4} M, [NaCl] = 0.10 M, pH = 7.0, T = 25°C. As expected, the two trends tend to overlap at low values of C_D/C_P because, under these circumstances, the polymer is present as a triplex in both systems. The trends become distinct at the highest values of C_D/C_P since the polymer is now present as a duplex in the poly(A)•poly(U)/coralyne system.
