Systems Biology x Network Biology GOAL: develop a quantitative understanding of the biological function of genetic and biochemical networks INPUT gene gene B gene C gene D gene E gene F OUTPUT function of gene product A-F can be known in detail but this is not sufficient to reveal the biological function of the inPUt-oUTPUt relation a system approach ( looking beyond one gene/protein) is necessary to reveal the biological function of this whole network what is the function of the individual interactions(feedbacks and feedforwards)in the context of the entire network?
