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.
1 Altitude is the angular distance of an object above the local horizon. It ranges from 0 degrees at the horizon to 90 degrees at the zenith, the spot directly overhead.  Azimuth is the angular distance of an object from the local North, measured along the horizon.
