briefly explain the formation of dna.

Solution
Fundamental unit of DNA is nucleotides.
Nucleotides are made up of three components:
1. Nitrogenous base (Adenine, Thymine, Guanine and Cytosine).
2. Pentose sugar.
3. Phosphate group.
Nitrogenous base and pentose sugar join together via N-glycosidic bond to form nucleoside.
Than nucleoside and phosphate group join together via phosphoester bond to form a nucleotide.
After nucleotides are formed, many nucleotides join together via phosphodiester bond to form a polynucleotide chain.
At last two polynucleotide chains twist around each other and nitrogenous base of one polynucleotide chain form a hydrogen bond with other chain to form a DNA.
