Deoxyribonucleic acid (DNA) is a biopolymer consisting of each nucleotide and, through Watson Crick hydrogen bonds, is combined with two other nucleotide monomers in polymer chain. Through phosphodiester connections, those nucleotides inside strands are connected to the 3' carbon of a sugar of a nuclear fibre by the hydroxyl group in the phosphate group, which forms an ester bond with the phosphate of another 5' end of the nuclear sugar carbon, and eliminates a molecule of water. The following three fundamental building components, such as an aromatic planar derivative of a pyrimidine (thymine & cytosine)/purine base (adenine & guanine), sugar deoxyribase, and a group of phosphates, constitute a nucleotide monomer. B-DNA is the most frequent type of conformational helix of the dsDNA base pair (Shamsi & Kraatz 2012) (Table 1.5).
