What is the role of translation elongation factors?
What is the role of translation elongation factors?
- They initiate translation.
- They terminate translation.
- They improve the efficiency and accuracy of translation. (correct)
- They form new peptide bonds.
What happens when there is a tight (correct) codon/anticodon pairing?
What happens when there is a tight (correct) codon/anticodon pairing?
