FIG. 3.

Side views of the 3D models of intact and digested N-RNA rings containing 10 subunits of N: (a) intact in yellow and (b) digested in orange. Next to the reconstructions are the averaged views (lower panel) and corresponding reprojections of each model (upper panel). The top view orientations are shown on the left, with the views progressively tilted, and ending with the side views on the right. There is excellent agreement between averaged views (actual data) and reprojections of the 3D structures (model). The protein density is in white.
