Summary:

The course will explain the principles of algorithms employed for processing biological data at the molecular level, in particular those algorithms that are used for genome sequencing, comparing of biological sequences (primarily genes), their probabilistic and grammatical modeling, for search of associations between primary and higher structures of proteins, their functions and interactions, for analyzing high-throughput data (mainly gene expression data) and for system-biological modeling of processes such as metabolism or gene expression regulation. The course will also cover some neccessary elements of molecular biology as well as basic principles of technologies for the measurement of data that are to be processed by the instructed algorithms.

Keywords:

genomic data, alignment, expression
