Class NUCLEIC-ACID-NUCLEOSIDE-OR-NUCLEOTIDE

A complex compound of high molecular weight occurring in living cells. These are basically of two types, ribonucleic (RNA) and deoxyribo-nucleic (DNA) acids, both of which consist of nucleotides (nucleoside phosphates linked together by phosphate bridges).
