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.
Combinations of these atoms form the sugar-phosphate backbone of the DNA -- the sides of the ladder, in other words. Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder.(It takes two bases to form a rung -- one for each side of the ladder.). A sugar molecule, a base, and a phosphate molecule group together to make up a nucleotide.Nucleotides are abundant in the cell's nucleus.ombinations of these atoms form the sugar-phosphate backbone of the DNA -- the sides of the ladder, in other words.
