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.
Part of the Mathematics glossary: Azimuth and elevation are angles used to define the apparent position of an object in the sky, relative to a specific observation point. The observer is usually (but not necessarily) located on the earth's surface.
