Structure of the VIR-576 created with Raswin Molecular Graphics. Windows version 2.7.5.2 The backbone traces are colored by Amino to Carboxy "rainbow", a spectral sequence of colors starting at the amino terminus (or 5' terminus of nucleic acid chains)(blue) and ending at the carboxy terminus (or 3' terminus)(red)

Then, an animated Gif was created with a sequence of 35 images.
