Presentation Transcript

  1. rRNA visualization for Bio 206 - Cell Biology Lab What kind of organism did this RNA come from?

  2. rRNA Visualization Goals • Familiarize students with gel electrophoresis principles • Connect lecture material (ribosomal function) with observable phenomena (bands of RNA on a gel) • Evolution connection (compare different organisms – bacteria, yeast, animal, plant)

  3. Beautiful stolen gel image big small

  4. Ribosomal RNA: a key to phylogeny (1993) “As molecular phylogeny increasingly shapes our understanding of organismal relationships, no molecule has been applied to more questions than have ribosomal RNAs.” GJ Olsen and CR Woese, 1993. FASEB Journal. 7, 113-123. Carl Woese

  5. Using rRNA
