- Course objectives
- Students will learn the basic knowledge about structure, dynamics and function of nucleic acids (DNA and RNA). The knowledge will be based on explanation of the recent state-of-the art experimental research, namely X-ray crystallography, NMR and structural bioinformatics. Students will also learn basic information about modern theoretical and computational methods. Students will obtain an overall overview of the field and selected case examples will be used to clarify the knowledge of structural dynamics of nucleic acids in biology and chemistry. These include local conformational variability of B-DNA, noncanonical nucleic acids, interactions of DNA with drugs, RNA enzymes, structure and function of the ribosome and regulatory role of RNA and DNA at different levels of genome expression.
- Learning outcomes
