deoxyribonucleic acid, desoxyribonucleic acid
the nucleic acid that constitutes the primary genetic material of most cellular organisms, any of various nucleic acids that are usually the molecular basis of heredity, are constructed of a double helix held together by hydrogen bonds between purine and pyrimidine bases (see BASE entry 1 sense 7b) which project inward from two chains containing alternate links of deoxyribose and phosphate, and that in eukaryotes are localized chiefly in cell nuclei, neljast deoksüribonukleotiidist (AMP, CMP, GMP ja TMP) koosnev polünukleotiid (molekulistruktuurilt kaksikspiraal), mille puriin‑ ja pürimidiinaluste moodustatavad koodonid (koodid) sisaldavad indiviidi genotüüpi, desoksüribonukleiinhappe molekul, millesse on salvestunud inimese pärilikkuse informatsioon
