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 two phosphate groups of ADP are added in series to the 5â carbon of the sugar backbone, while the adenosine molecule attaches to the 1â carbon. The two phosphates in ADP can be correlated with ATP and AMP. ATP consists of three phosphate groups attached in series to the 5â carbon location, whereas ADP contains two phosphate groups attached to the 5â position, and AMP contains only one phosphate group attached at the 5â position.
