Our observation suggests a particular microscopic mechanism for the observed universal global topology in these networks. The numerical data and analytical solution of our model disagree with a simple power-law for the experimentally obtained degree distribution in the case of yeast.PhysicsConference proceeding1873-21192538434000283853
