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.
An azimuth is defined as a horizontal angle measured clockwise from a north base line. This north base line could be true north, magnetic north, or grid north. The azimuth is the most common military method to express direction. When using an azimuth, the point from which the azimuth originates is the center of an imaginary circle . This circle is divided into 360 degrees or 6400 mils . Figure 6-2. Origin of azimuth circle. a. Back Azimuth. A back azimuth is the opposite direction of an azimuth. It is comparable to doing about face. To obtain a back azimuth from an azimuth, add 180 degrees if the azimuth is 180 degrees or less, or subtract 180 degrees if the azimuth is 180 degrees or more .
