Рибонуклеиновые кислоты

Рибонуклеиновые кислоты [PHK(RNA)] представляют собой полимеры из нуклеозид-фосфатных звеньев, соединённых фосфодиэфирной связью (см. Азотистые основания и нуклеотиды). В качестве азотистых оснований в РНК присутствуют урацил, цитозин, аденин ...

 
А. Рибонуклеиновые кислоты

РНК принимают участие во всех стадиях процесса генной экспрессии и биосинтеза белка (см. Молекулярная генетика: общие сведения). Свойства наиболее важных видов РНК приведены в таблице. Кроме того, здесь схематически показаны вторичные структуры ...

Б. Транспортные РНК (tRNAPhe)

Транспортные РНК [тРНК (tRNA)] участвуют в процессе трансляции в качестве промежуточного связующего звена между нуклеиновыми кислотами и белками. Это небольшие молекулы РНК из 70-90 нуклеотидов, которые с помощью своих ...
