Presentation Transcript

  1. Gene Expression

  2. DNA vs. RNA

  3. Making Proteins • Polypeptides • Unedited • Editing occurs in one of two places • Transcriptional • Post translational

  4. Transcriptional Editing • TATA Box • Tells RNA polymerase where to begin transcribing

  5. Transcriptional Editing • Transcription • Introns are removed • Exons remain and get translated • mRNA is formed from exons • (Yes the name seems rather backwards!)

  6. Making Proteins • Post translational • Many different things can happen • Removal of portions • Alteration of functional groups on polypeptide • Glutamic acid can become selenated • Alters folding patterns

  7. The Central Dogma of Biology DNA mRNA Polypeptide

  8. What does it mean? • Are we only a product of our genes? • What is purely genetic? • What is purely environmental?

  9. Dr. Seuss Lab
