DNA-polymerases

DNA-polymerases
ДНК-полимеразы — ферменты, участвующие в синтезе ДНК. У E. coli были выделены 3 типа ДНК-п.: polI, polII и pol III. Pol III является основным ферментом, ответственным за репликацию ДНК в клетке бактерий. Два др. фермента функционируют преимущественно при восстановлении (репарации) ДНК. Эукариоты содержат множество видов ДНК-п., находящихся в разных частях клетки: в ядре, цитоплазме или митохондриях, и выполняют различные функции, такие, как репликация, репарация и рекомбинация.
