Answer :
nucleic acids are long chains made of individual, repeated units called monomers. The particular name for the units of nucleic acids are called nucleotides and each contains three things: a phosphate group, a sugar (deoxyribose in DNA and ribose in RNA) and a nitrogenous base.
Nucleic acids are chainlike molecules whose major function is the storage and expression of genomic information.
Structure and Function of Nucleic acids
Nucleic acids are polynucleotides—simply put, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each of the nucleotide block consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.
Nucleotides play an essential role in cells and viruses and a major function of nucleic acids is the storage and expression of genomic information.
