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 phosphate group of one nucleotide links to the deoxyribose unit of another to form the backbone of the DNA strand. The nucleobases form the ladder rungs when the two strands align and twist to form the classical double-helix structure.
