1) basis, ground, foundation2) base, foundation ( нижняя часть предмета)3) хим. baseПары оснований ( пурины и пиримидины), объединяющиеся через водородные связи в двухцепочечную нуклеиновую кислоту. Комплементарны следующие пары оснований: гуанин и цитозин, аденин и тимин, аденин и урацил.
Нуклеотиды, отличающиеся по структуре от четырёх первичных строительных элементов нуклеиновых кислот; имеются в РНК, где модификации осуществляются после транскрипции и в ДНК (например, метилированные или глюкозилированные минорные осннования).
Два комплементарных, соединённых водородными связями основания в ДНК или РНК.
Взаимодействие через водородное связывание между противоположными пуриновыми и пиримидиновыми основаниями в нуклеиновых кислотах.
Соотношение между числом адениновых и тиминовых остатков (A + T) и числом гуаниновых и цитозиновых остатков (G + C) в двухцепочечной ДНК.
