The aim of the lecture is to provide a first insight into systems biology. We will focus primarily on the structure of regulatory networks, their global properties, and the enrichment of network motifs. Using real examples, we will study frequently recurring motifs, explain their functions, and discuss the reasons why they are evolutionarily conserved. We will examine the mechanisms by which robustness is achieved in these networks and how they are evolutionarily optimized.
