Presentation Transcript

  1. Lecture 17: RNA and Transcription

  2. Announcements Doodle poll for changing date of final

  3. DNA replication in eukaryotes:replicating the telomeres The problem: The solution: new lagging strand is shorter

  4. Review of RNA structure

  5. RNA secondary structure = hairpin or stem-loop

  6. Only one DNA strand is the template also called the coding strand

  7. Overview of transcription

  8. Multiple transcripts produced simulateneously

  9. E. Coli promoter region

  10. Transcription initiation in E. Coli

  11. Elongation and termination Transcript termination sequence forms a hairpin

  12. Transcription initiation in eukaryotes formation of the PIC promoter clearance

  13. Co-transcriptional processing

  14. Exon/intron boundaries have conserved sequences
