Advanced course covering RNA molecules and their versatile roles in the eukaryotic cell. In the itroductory lecture unique RNA characteristics enabling the existence of the RNA world and its final transition into current DNA-RNA-protein world will be discussed. Later on, current state of knowledge on various RNA species and their activities within the cellular metabolism, mainly in the hierarchical regulation of gene expression, will be summarised.

The course is primarily taught in Czech. However, in case English-speaking students sign in, the course will be taught in English. The presentations are in English.
