Figure 2From: RNA FRABASE 2.0: an advanced web-accessible database with the capacity to search the three-dimensional fragments within RNA structuresAn example of the RNA secondary structure which includes residues with missing coordinates (2A64). The figure illustrates a graphic image of the secondary structure (top), the sequence (middle) and dot-bracket representation of the secondary structure (bottom) for he 2A64 RNA molecule. The residues missing from the PDB file coordinate section are marked in red.Back to article page
