Preface

An ultimate goal of a molecular biologist is to use genetic data in order to reveal fundamental cellular processes, and their impact on complex organisms. In order to achieve this goal one has to study complex systems of several genes and proteins, which carry out a specific function, rather than single genes. Such research can help identify proteins and genes associated with human diseases, which has huge practical importance.  

Gene networks describe functional pathways in a given cell or tissue, representing processes such as metabolism, gene regulation, transport and signal transduction.
