Genetische Schaltkreise kontrollieren die Aktivität von Genen und damit die Funktion von Zellen und Organismen. Wissenschaftler vom Max-Planck-Institut für Kolloid- und Grenzflächenforschung in Potsdam und der University of California in San Diego zeigen, wie Wachstumseffekte die genetischen Schaltkreise in einer Bakterienzelle beeinflussen. Demnach können Gene auch ohne Regulierung unterschiedlich aktiv sein - je nachdem, ob sie in schnell oder langsam wachsenden Zellen in Proteine übersetzt werden. Mit diesen Ergebnissen können die Forscher besser verstehen, wie Zellen ihre Gene regulieren, und so künftig künstliche genetische Schaltkreise entwickeln. (Cell, 24. Dezember 2009)
