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 OH on the third carbon will bond to the phosphate group of other nucleotides. The OH group on the fourth carbon is involved in the closure of the ring. The OH group on the fifth carbon is what bonds to the phosphate unit of this particular nucleotide.
