Systems Biology


System Biology is the branch of science that seeks to understand biological organisms at all levels, since the characterization of its constituent parts (genes, RNAs, proteins, metabolites), the elucidation of the interconnections between the different members of the network of gene regulation until the comprehension of the organism as a whole.

Biological systems
 are dynamic, using complex cellular circuits to implement various functionshow to grow, differentiate and reproduce. High-throughput technologies that exploit data from transcriptomeproteome, protein-protein, protein-DNA, protein-RNA interactionsamong others, represent powerful tools for the systemic analysisHowever, each of these individual data sets do not reflect a global view of cell behaviorsince that complexity of living organisms is an emergent property, inherent not only genes, RNAs, proteins or metabolitesbut is a consequence of their actions and interactions.

To face this challenge, the systems biology uses a multidisciplinary approach, using molecular tools, computational mathematics and statistics, to create quantitative models that integrate the various data accumulated and describe the behavior of living organisms in response to environmental disturbances.
