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