Question
What are nucleic acids ?

Answer

Nucleic acids are molecular weight macropolymers. These are of mainly deoxyribose nucleic acid and ribose nucleic acid. These are also called polynucleotides, because these are polymers of long chains of nucleotides. Both types of nucleic acids have three main components pentose sugar, nitrogeneous base and phosphate group.
RNA molecules have ribose sugar, white DNA molecules have deoxyribose sugars. DNA have four bases : adenine (A), guanine (G), cytosine (C) and thyamine (T). First three bases of RNA are same but fourth base is uracil.
Nucleic acids are present in the nucleus of living cells. Genetic information of the living organisms is stored in nucleic acids.
