Absolute location describes the position of a place in a way that never changes, no matter your location. The location is identified by specific coordinates. The most common coordinate system is longitude and latitude, which describes a specific place on the earth's surface.
Nucleic Acids. Nucleotides join together through phosphodiester linkages between the 5' and 3' carbon atoms to form nucleic acids. The 3' -OH of the sugar group forms a bond with one of the negatively charged oxygens of the phosphate group attached to the 5' carbon of another sugar.
During the construction of a new DNA strand, a molecule called a hydroxyl group (which contains an oxygen atom and a hydrogen atom) attaches to the sugar of the last dNTP in the strand and chemically binds to the phosphate group on the next dNTP.
