Learning objectives
This course aims to provide students with the basic knowledge of fundamental characteristics of living organisms. In particular, it aims to provide students with the basic knowledge of fundamental biological structures - biological molecules, cells, tissues - and their functioning.
Expected learning outcomes
At the end of the course, students will gain knowledge of the main inorganic and organic components of living organisms, nucleic acid and protein synthesis and related basic regulation, the main functions of nucleic acids and proteins, and transmission of information from DNA to proteins, both in prokaryotic and eukaryotic cells. Students will also gain knowledge of the molecular organization and functions of subcellular organelles and membrane systems in both prokaryotic and eukaryotic cells as well as cell division processes of eukaryotic cells.
