Das Erbgutmolekül enthält den Bauplan des Lebens. Wie der Bauplan in der Zelle verpackt ist, bestimmt auch, welche Gene aktiv sind und welche stumm geschaltet werden. Gerät die Struktur durcheinander, können Krankheiten wie etwa Krebs entstehen. Münchner Wissenschaftlerinnen und Wissenschaftlern ist es gelungen, mithilfe einer aus DNA konstruierten molekularen Pinzette Interaktionen auf der ersten Verpackungsebene des Erbguts zu messen.
Zwei Meter des Moleküls Desoxyribonukleinsäure (DNA), der Trägerin unserer Erbinformation, befinden sich in jedem Kern einer menschlichen Zelle. Die DNA muss daher sorgsam verpackt werden.
