Tree number(s): D13.444.308
Scope note: A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
Annotation: general; prefer specifics; /biosyn permitted but consider also DNA REPLICATION; structural DNA models = DNA (IM) + MOLECULAR MODELS (IM)
