Question

Arrange the following events in the order of synthesis of a protein
i) A peptide bond forms
ii) A tRNA matches its anticodon to the codon in the A- site
iii) The movement of second tRNA complex from A-site to P-site
iv) The large subunit attaches to the small subunit and the initiator tRNA fits in the P-site
v) A small subunit binds to the mRNA
vi) The activated amino acid tRNA complex attaches the initiation codon on mRNA

• A. iv, v, iii, ii, i, vi
• B. iv, vi, v, ii, I, iii
• C. v, iv, iii, ii, vi, i
• D. v, vi, iv, ii, i, iii

Answer 1

The correct option is D v, vi, iv, ii, i, iii

Events in the order of synthesis of a protein: A small subunit binds to the mRNA $\to$ The activated amino acid tRNA complex attaches the initiation codon on mRNA $\to$ The large subunit attaches to the small subunit and the initiator tRNA fits in the P-site $\to$ A tRNA matches its anticodon to the codon in the A- site $\to$ A peptide bond forms $\to$ The movement of second tRNA complex from A-site to P-site.
