Die DNA bildet auch bei Bakterien die bekannte Doppelhelix, allerdings ist sie ringförmig. Man kann also durchaus von einem Chromosom sprechen.
Ganz frei ist sie auch nicht, sondern zumindest bei einigen Bakteriengruppen an der Zellmenbran angeheftet.
Allerdings ist sie nicht von einer Hülle umgeben, wie die Kernhülle bei Eukaryonten, daher spricht man von “frei”.
Plasmide sind einfach weitere “Chromosomen”, die sich genau so verhalten wie das “Hauptchromosom”.
