Today we finished chapter 12, on RNA processing.
We discussed the process of intron splicing, in which snRNPs ("snurps") play an important role, the different mechanisms of alternative splicing (promoter selection, tail site selection, exon cassette selection, trans-splicing), base modification (methylation and pseudo-urydilation), RNA editing, export of RNA to the cytoplasm, and mRNA degradation (in prokaryotes and eukaryotes).
