Question

The following features occur during protein synthesis:
(i) Movement of m-RNA from the nucleus into the cytoplasm, where it binds to the ribosomes
(ii) Formation of amino acyl t-RNA complex
(iii) Transcription of specific segments of DNA into m-RNA molecules in the nucleus
(iv) Binding of N-terminal amino acid, methionine t-RNA to the 'P' site of the ribosome. The t-RNA anticodon "pairs with AUG on m-RNA"
(v) Formation of peptide bond between first and second amino acids at the 'A' site
(vi) Release of the completed polypeptide chain from ribosomes
(vii) Migration of dipeptide to form a tripeptide and then a polypeptide
The correct order of events is

• A. (iii) - (ii) - (i) - (iv) - (v) - (vi) - (vii)
• B. (i) - (ii) - (iii) - (iv) - (v) - (vi) - (vii)
• C. (iii) - (i) - (ii) - (iv) - (v) - (vi) - (vii)
• D. (iii) - (i) - (ii) - (iv) - (v) - (vii) - (vi)
