FIG. 3.

Comparison between the “real” excess amplitude $\tilde{F}\left(q\right)=\sqrt{I\left(q\right)}$ (red) with the sum of component amplitudes ${\tilde{F}}_k\left(q\right)=\sqrt{I_k\left(q\right)}$ (black) for lysozyme (left) and DNA (right) using calculated profiles from 3D-RISM. For Lys, k is solu and hyd; while for DNA there are also counter-ion (Na⁺) and co-ion (Cl⁻). The difference between these two is plotted in the inset (blue).
