Over the last decades, a number of technologies to study DNA, RNA, proteins, metabolites and their interactions has been developed. To understand life at the molecular level, they have been applied in numerous biological and biomedical experiments. Much of the resulting data, as well as the knowledge gained in these experiments, are freely available for researchers in the form of computer databases and tools. Analysis and interpretation of experimental data in biology increasingly depends on using these bioinformatics methods efficiently and effectively. In this course, students will be given a broad overview of the field of bioinformatics, with a focus on practical application and interpretation of results from tools used in everyday biological research.
