From a Biological Point of View, the Following Points Are
Generally Important
1. Bioinformatics analyzes biological systems. However, these all behave similarly in
principle. What are the principles? How and with which software do I get the system
behavior out? It is very important that a biological system adapts to the environment as
optimally as possible and actively controls itself. These capabilities do not reside in
individual components, but only emerge through the interaction of all parts (emer
gence). Pioneers of systems biology have summarized these principles (Chap. 9).
2. Every living being today is the result of millions of years of evolution of the population
that produced it. Therefore, a good bioinformatics strategy is also to look at the evolu
tion of a protein sequence, a protein structure, an organism. We will learn basic tech
niques for this (Chap. 10).
3. Finally, we can also look at the concrete implementation of design principles in a cell
to efficiently address bioinformatics problems, i.e., in particular, to understand which
molecular component we are looking at and how it acts in the cell. For this, we look at
the flow of genetic information from genome to RNA to protein, as well as the control
of genetic information and gene expression data. We look at how proteins find their
place in the cell, how the cell moves, organizes metabolism and differentiates. Again,
the information that is important for each of these can be quickly analyzed and recog
nized using bioinformatics algorithms (e.g., localization signals, enzyme network
lookup in biochemical metabolism database, and even use it to make custom proteins;
Chap. 11).
This lays the foundation for Part III, which explores fascinating results and current
developments in bioinformatics.
