Structures are displayed using the RCSB Mol* application. By default, NDB residue colors are shown for nucleic acid residues (A/DA:red, DT:blue, U:cyan, G/DG:green, C/DC:yellow, nonstandard:fuschia).
Click on any residue/atom to view its local detail.
The window icon enables toggling between regular and full window display.
The wrench icon opens/closes the display options menu. Density maps can be turned on for X-ray and EM structures that have associated experimental data available.
