Prokaryotic and Eukaryotic mRNAs

Prokaryotic and Eukaryotic mRNAs. Overview of Translation. Signals for Translation Initiation. Start codon. Initiation of Translation Initiation is controlled differently in prokaryotic and eukaryotic ribosomes. In prokaryotes a single transcript can give rise to multiple proteins.

Presentation Transcript

  1. Prokaryotic and Eukaryotic mRNAs

  2. Overview of Translation

  3. Signals for Translation Initiation Start codon

  4. Initiation of Translation Initiation is controlled differently in prokaryotic and eukaryotic ribosomes In prokaryotes a single transcript can give rise to multiple proteins

  5. Polysomes

  6. Ribosomal Frameshifting Because translation uses a triplet code, there are three potential reading frames in each mRNA

  7. In addition to the APE sites there is an mRNA binding groove that holds onto the message being translated Three tRNA binding sites: A site = amino-acyl tRNA binding site P site = peptidyl-tRNA binding site E site = exit site

  8. Procariotas

  9. Eucariotas

  10. Terminação

  11. Action of Chaperones during Translation

  12. Action of Chaperones during Protein Transport

  13. Overview of Protein Sorting
