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.
In chemical reactions, the phosphate group will attach to one reactant, giving it energy and allowing it to react with a second atom or molecule. A product is made through that chemical work. All these types of cellular work require ATP. The phosphate group is released after the work is done.
