What is the role of the release factor in the translation process?
Options
- ABinds to the start codon to initiate translation
- BHelps in the formation of peptide bond
- CBinds to the stop codon to terminate translation
- DAdds amino acids to the polypeptide chain
Correct answer
C. Binds to the stop codon to terminate translation
Step-by-step solution
For initiation, the ribosome binds to the mRNA at the start codon (AUG) that is recognised only by the initiator tRNA. The ribosome proceeds to the elongation phase of protein synthesis. During this stage, complexes composed of an amino acid linked to tRNA, sequentially bind to the appropriate codon in mRNA by forming complementary base pairs with the tRNA anticodon. The ribosome moves from codon to codon along the mRNA. Amino acids are added one by one, translated into Polypeptide sequences dictated by DNA and rep
