Lecture, chapter 12 - RNA processing

Today we started covering chapter 12, on RNA processing.

We discussed the kinds of processing that different RNA molecules undergo, in both eukaryotes and prokaryotes. We compared the kinds of RNA found in bacteria (regulatory RNA and tmRNA) with those find in eukaryotes (snRNA, snoRNA, scRNA, miRNA, siRNA...), of course, besides the "classics": tRNA, rRNA and mRNA, present in all cells.

We discussed mRNA processing more in depth than in previous chapters, and we introduced the basics of rRNA and tRNA post-transcriptional processing. When focused on mRNA we talked about 5'-capping and polyadenylation ("tailing"). On Friday, we'll talk about intron splicing.
