Course objectives
The course aims to overview the molecular basis of various processes and pathways in eukaryotic cells; such overview serves as basis to understand general principles controling functions of cells in multicellular organisms.
Learning outcomes
At the end of the course students will acquire general knowledge on recent developments within the field of molecular biology of eukaryotic cell. He/she will understand molecular mechanisms of cell cycle and principles of its regulation, structure of DNA in chromatin, principles of signal transduction and programmed cell death. Using this knowledge, he/she should describe and discuss mechanisms of cancerogenesis be able to delineate the major differences between healthy and cancer cells. In addition, students will understand the ways how eukaryotic cells communicate with neighbour cells and extracellular matrix and principles of protein folding, traficking and degradation.
Syllabus
