Lecture, chapter 12 - Processing of RNA

Today we talked about how introns are removed by using a combination of small nuclear RNA (snRNA) and proteins called small nuclear ribonucleoproteins (snRNP, a.k.a. "snurps").

Then we discussed alternative RNA splicing mechanisms:
  • Alternative promoter selection
  • Alternative tail site selection
  • Alternative splicing by exon cassette selection
  • Trans-splicing (rare)

On Friday: Molecular techniques!
