Extended Data Figure 6. The nucleotide densities in all states.

The nucleotide densities fitting with atomic models are shown with blue meshes. All close-up views were directly screen-copied from Coot⁵⁸ after atomic modelling into the density maps without further modification or beautification. At the common contour level used for atomic modelling, the potential nucleotide densities in the apo-like subunits are mostly out, albeit they can show up partial nucleotide shapes at much lower contour level.
