| nucleic acids | Highly complex portions of nucleoproteins that yield a mixture of purines and pyrimidines, a ribose or deoxyribose component, and phosphoric acid on complete hydrolysis. The two general types are ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). (12 Dec 1998) |
| nucleic acids, nucleotides, and nucleosides | Complex compounds of high molecular weight occurring in living cells. These are basically of two types, ribonucleic (RNA) and deoxyribonucleic (DNA) acids, both of which consist of nucleotides (nucleoside phosphates linked together by phosphate bridges).
