Answer:
Each nucleotide consists of three components:
a nitrogenous base: cytosine (C), guanine (G), adenine (A) or thymine (T)
a five-carbon sugar molecule (deoxyribose in the case of DNA)
a phosphate molecule
The backbone of the polynucleotide is a chain of sugar and phosphate molecules. Each of the sugar groups in this sugar-phosphate backbone is linked to one of the four nitrogenous bases.
DNA's ability to store - and transmit - information lies in the fact that it consists of two polynucleotide strands that twist around each other to form a double-stranded helix. The bases link across the two strands in a specific manner using hydrogen bonds: cytosine (C) pairs with guanine (G), and adenine (A) pairs with thymine (T).
The double helix of the complete DNA molecule resembles a spiral staircase, with two sugar phosphate backbones and the paired bases in the centre of the helix. This structure explains two of the most important properties of the molecule. First, it can be copied or 'replicated', as each strand can act as a template for the generation of the complementary strand. Second, it can store information in the linear sequence of the nucleotides along each strand.
