  1. Transcription and Translation IB Biology Higher Level

  2. Starter – try thecut and paste DNA replicationessay

  3. LearningObjectives Everyoneshould • Statethat transcription is carried out in a direction. • Statethat eukaryotic RNA needs the removal of introns to form mature mRNA. Mostwill • Distinguishbetween the sense and antisense strands of DNA. Somemight • Explainthe process of transcription in prokaryotes, including the role of the promoter region, RNA polymerase, nucleoside triphosphates and the terminator.

  4. Individual activity • Complete the Transcription exercise • Writethestatementsintothespaceprovided in thecorrectorder

  5. STARTER Make sure section 7.2 and 7.3 are complete in your key word glossary

  6. STARTER: Reviewquiz! • 1. transcription, RNA polymerase • 2. ligase • 3. C C U G A C U A A • 4. transfer RNA • 5. 20, 4 • 6. A pairswith T, G pairswith C • 7. DNA • 8. anticodon • 9. laggingstrand, ligase • 10. 64

  7. LearningObjectives Everyoneshould • Statethat translation consists of initiation, elongation, translocation and termination • Statethat translation occurs in a direction. Mostwill • Outlinethe structure of ribosomes, including protein and RNA composition, large and small subunits, three tRNA binding sites and mRNA binding sites. Somemight • Explainthat each tRNA molecule is recognized by a tRNA-activating enzyme that binds a specific amino acid to the tRNA, using ATP for energy. • Explainthe process of translation, including ribosomes, polysomes, start codons and stop codons.

  8. Individual Tasks • Complete the Translation Cloze exercise • Make sure your key word glossary is complete up to 7.5
