Nucleotida sunt moleculae organicae primae acidorum nucleicorum, sit ADN aut ARN, inter se congregantes millenis et millenis earum, partibus tribus conficta: pentosa, acidum phosphoricum, et unum tantum horum: guaninum (G), adeninum (A), cytosinum (C), thyminum (T), uracilum (U). Etiam, viis metabolicis sat prosunt, ut conditoria energetica adhibita, verbi gratia ATP, aut in signis cellularibus juvantia.
Nucleobases
In natura imprimis quinque nucleobases inveniuntur, ex quibus intra ADN quattuor quinque inveniuntur: guaninum, adeninum, cytosinum, thyminum. Nuper synthesis ADN Hachimojiensis (ADN octonarii) dicti, ADN ex nucleobasibus naturalibus communiter cum adhuc incognitis nucleobasibus constitutum, isoguanino enim et 6-amino-5-nitropyridino-2-olo et 1-methylocytosino et 2-aminoimidazo[1,2-a][1,3,5]triazino-4(1H)-ono (dS)[1]), consecuta est[2].
