Emphasizing computational methods, Systems Biology and Bioinformatics provides an introduction to system biology and its impact on biology and medicine. The book reviews the basic principles of molecular and cell biology using a system-oriented approach, with a brief description of the high-throughput biological experiments that produce databases. The methods presented in the text include techniques to discover genes, perform nucleotide and amino acid sequence matching, and estimate static gene dynamic pathways. The book also explains how to use system-oriented models to predict the behavior of biological systems for important applications such as rational drug design.
