This is a 3D computer graphic model of a ribosome. Ribosomes are composed of protein and RNA. They consist of subunits that fit together and work as one to translate mRNA (messenger RNA) into a polypeptide chain during protein synthesis (translation).
The azimuth originates at true North. The azimuth originates form the north point. It is a measure of how far an object is form the observer's north point.
For the band, see Azimuth (band). The azimuth is the angle formed between a reference direction (north) and a line from the observer to a point of interest projected on the same plane as the reference direction orthogonal to the zenith.
