ácido desoxirribonucleico
Scope note: Polímero de desoxirribonucleótidos que es el material genético principal de todas las células. Los organismos eucariotas y procariotas suelen contener ADN en forma de doble cadena, aunque en varios procesos biológicos importantes participan transitoriamente regiones de una sola cadena. El ADN, que consiste en un esqueleto de poliazúcar-fosfato, posee proyecciones de purinas (adenina y guanina) y pirimidinas (timina y citosina) y forma una doble hélice que se mantiene unida por puentes de hidrógeno entre estas purinas y pirimidinas (adenina con timina y guanina con citosina).

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).
