Three turns of the helical ribgrass mosaic virus (pdb identifier 1rmv) are shown using the Chimera multiscale extension. The three turns contain exactly 49 subunits. A complete virus has approximately 2100 subunits. The black coil is RNA. The red and yellow are the same protein represented using transparent surfaces with different resolutions. Different colors were used so that the subunits are easily distinguished. The blue ribbon shows the secondary structure of 3 copies of the protein.
