What are the building blocks for nucleic acids DNA and RNA?

DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are polymers of nucleotides linked in a chain through phosphodiester bonds. In biological systems, they serve as information-carrying molecules or, in the case of some RNA molecules, catalysts. This brief review will focus on aspects of structure of particular importance in manipulating DNA.

Nucleotides are the building blocks of all nucleic acids.
