"Systems biology is a means of understanding the dynamic interactions between the components of a living system and, also, between living systems and their interactions with the environment.
It is an approach by which biological questions are addressed through integrating experiments in iterative cycles with computational modelling, simulation and theory. Modelling is not the final goal, but it is a tool to increase understanding of the system, to develop more directed experiments and, finally, allow predictions.
Intrinsic to systems biology is its interdisciplinary nature and the common aim of achieving the quantitative understanding of dynamic biological processes, through the use of mathematical and statistical analyses to integrate biological data, in order to develop predictive models of biological behaviour.
