(PresseBox) (Freiburg, )
Freiburger Wissenschaftler haben eine neue Art der Regulation in Zellen entdeckt, bei der ein regulatorischer Faktor räumlich von seinem Zielort getrennt wird, jedoch im selben Abteil der Zelle verbleibt. Um sich zu vermehren, muss jede Zelle ihr Erbgut verdoppeln und auf jede Tochterzelle verteilen. Egel ob ein Chromosom, wie in vielen Bakterien, oder viele Chromosomen wie in menschlichen Zellen - der Beginn der Replikation, der Erbgutverdopplung, muss exakt kontrolliert werden. Wichtig ist ebenfalls, dass Zellen nur einmal die Replikation beginnen und nicht mehrfach. Eine erneute Initiation kann zur Entstehung von Krebs führen oder gar zum Zelltod.
