WebTraductions en contexte de "bactéries qui possèdent une" en français-anglais avec Reverso Context : Il existe cependant des bactéries qui possèdent une photosynthèse anoxygénique, laquelle consomme du CO2 mais ne libère pas d'O2. Reverse gyrase is a type I topoisomerase that introduces positive supercoils into DNA, contrary to the typical negative supercoils introduced by the type II topoisomerase DNA gyrase. These positive supercoils can be introduced to DNA that is either negatively supercoiled or fully relaxed. Where DNA gyrase forms a tetramer and is capable of cleaving a double-stranded region of DNA, reverse gyrase can only cleave single stranded DNA. More specifically, reverse gyrase is a me…
