RNA Splicing and Processing: Mechanisms and Regulation

This lecture covers the mechanisms of RNA splicing and processing in eukaryotic cells, focusing on the removal of introns and the splicing of exons to form mature messenger RNA. It explains the role of small nuclear ribonucleoproteins (snRNPs) and the spliceosome in the splicing process. Alternative splicing and its impact on protein diversity are also discussed, along with the nuclear export of fully spliced RNA for translation. The lecture delves into the structure and function of ribosomes in translation, emphasizing the different binding sites for tRNA and the process of initiation, elongation, and termination. Additionally, it highlights the composition and differences between eukaryotic and prokaryotic ribosomes.
