Chromatin ist nicht unbeweglich. Es handelt sich um ein hochdynamisches Material, dessen 3D-Struktur zentrale genomische Prozesse – von der Transkription bis zur DNA-Reparatur – steuert. Doch wie verhält sich Chromatin als Material – als Flüssigkeit, Feststoff oder viskoelastisches Gel –, um diese Funktionen in lebenden Zellen auszuführen? Ohne eine Antwort auf diese Frage können wir nicht vollständig verstehen, wie Chromatin bei Krankheiten gestört wird.
