Zusammenfassung
Wir wissen viel über die Regulation der Genexpression bei Prokaryonten, aber relativ wenig darüber bei Eukaryonten. Wie wir sehen werden, ist das Operonsystem der Genregulation bei Eukaryonten nicht anwendbar. Eukaryonten sind bezüglich der Organisation ihrer Zellen komplexer gebaut als Prokaryonten. Ihre Zellen sind durch viele Membransysteme in Kompartimente unterteilt. Von besonderem Interesse ist der Zellkern, der die Hauptmasse des genetischen Materials enthält. Diese Kompartimentierung hat Folgen für die Regulation der Genexpression. Wir wollen im folgenden die Wirkorte zusammenfassen, an denen Regulation eingreifen kann oder könnte, um die Enzymsynthese in tierischen Zellen zu kontrollieren.
