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.
The sugar carbon atoms are numbered 1 to 5, with 1 being the point of attachment of the nitrogenous base, and 5 the point of attachment of the phosphate group. DNA polymers are built from individual nucleotides by linking the phosphate of one nucleotide to the #3 carbon of the neighboring nucleotide. The repeating pattern of phosphate, sugar, then phosphate again is commonly referred to as the backbone of the molecule. The sugar in DNA is deoxyribose.
