Questions and Answers

What are the differences in composition of bacterial and eukaryotic ribosomes and translation factors?

  • Eukaryotic ribosomes are smaller and contain translation factors
  • Bacterial ribosomes are smaller and lack translation factors
  • Eukaryotic ribosomes are smaller and lack translation factors
  • Bacterial ribosomes are larger and lack translation factors (correct)

    • During which phase does translation occur?

  • Elongation phase (correct)
  • Initiation phase
  • Transcription phase
  • Replication phase

    • How is correct start codon selection ensured during translation initiation?

  • Through interaction with the termination factor
  • Through base pairing between the start codon and initiator tRNA (correct)
  • Through binding of the incorrect start codon by the initiation factor
  • Through random selection by the ribosome
