Since the carbons in the sugar are numbered one to five, the sugar end of the strand is called the 3' end and the phosphate end of the strand is called the 5' end. When two strands pair together because they are antiparallel, where one stand begins with a 5' phosphate group, the other will have a 3' OH group, and at the opposite end, the first strand will have a 3' OH group while the second has a 5' phosphate group. The four bases that make up this code are adenine (A), thymine (T), guanine (G) and cytosine (C). Gradientcorrected density functional computations with triplezetatype basis sets were performed to determine the preferred protonation site and the absolute gasphase proton affinities of the most stable tautomer of the DNA bases thymine (T), cytosine (C), adenine (A), and guanine (G). The main difference between adenine and guanine is that adenine contains an amine group on C-6, and an additional double bond between N-1 and C-6 in its pyrimidine ring whereas guanine contains an amine group on C-2 and a carbonyl group on C-6 in its pyrimidine . Because of the alternating nature of the phosphate groups and sugars in the backbone of nucleic acids, a nucleic acid strand has directionality.

Notice that the specific positioning required for hydrogen bonding is only made possible by the inverted nature of one of the two strands. Kossel was the first scientist to discover the five nucleotides adenosine, thymine, guanine, cytosine, and uracil the only letters used in writing the genomic instructions for every living thing on Earth. However, the nitrogenous bases can't hydrogen-bond in this orientation. The four bases are incorporated into DNA as nucleotides. Molecular biology is the study of Biology at molecular level. If we represent the strands as arrows with the arrowhead at the 3' end of the stand, we can see that the strands in a DNA molecule are organized antiparallel relative to each other. Each of the base pairs in a typical double-helix DNA comprises a purine and a pyrimidine: either an A paired with a T or a C paired with a G. These purine-pyrimidine pairs, which are called base complements, connect the two strands of the helix and are often compared to the rungs of a ladder. One or more phosphate .
