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.
A phosphate group, a five carbon sugar(Ribose in the case of RNA and deoxyribose in the case of DNA), and a nitrogen containing base(the bit that determines which kind of nucleotide it is. The phosphates and sugars bond together in a chain to create the outsides of the double helix of DNA.
