G3: Frontiers in RNA Biology – 13186
(2 hrs/week; 2 CP; Fall 2023)
M. Bühler, H. Grosshans
The discovery that RNA is not only a carrier of genetic information or a structural scaffold in ribonucleoprotein particles but can also act as a catalyst in many different cellular processes, greatly stimulated research on the structure, processing and function of RNA. The lecture will cover the following topics: chemistry and structure of RNA; major classes of cellular RNAs (mRNAs, tRNAs, rRNAs, snRNAs, and the newly discovered small regulatory ~20-nt RNAs); chemistry and structure of RNA; pre-mRNA processing with emphasis on splicing and polyadenylation; biogenesis of tRNA and rRNA; biochemistry and function of RNA interference (RNAi) and microRNAs; RNA trafficking in the cell, RNA quality control and RNA degradation; and regulated mRNA translation during development. Also covered are RNA-protein interactions and major classes of ribonucleoprotein particles and the evolution of RNAs.
