The DNA is the longest biopolymer discovered. It is made up of two strands that are the polymers of repeating units of deoxyribonucleotides. The deoxyribonucleotides, themselves consist of three moieties:
1. Deoxyribose Sugar: A pentose (5 carbon) Sugar
2. Phosphate: Phosphate group imparts the negative charge to DNA molecule
3. Nitrogenous Bases: These are aromatic compounds that have their basic nature due the presence of Nitrogen.
Two types of bases are found in the DNA molecule
1. Pyrimidine: they are single ringed compounds that are derivative of compound called Pyrimidine. There are two types of Pyrimidines in DNA, Cytosine and Thymine.
2. Purines: Purines are derivative of organic compounds called as Purines and have two rings. There are two Purines: Adenine and Guanine) in DNA.
The dexoribonucleotides are linked by the reaction of Phosphodiester bond to form one strand of DNA>
