Question

Given below are the steps of protein synthesis. Arrange them in correct sequence and select the correct option.
(i) Codon-anticodon reaction between $mRNA$ and aminoacyl $tRNA $ complex.
(ii) Attachment of $mRNA$ and smaller sub-unit of ribosome.
(iii) Charging or aminoacylation of $tRNA$.
(iv) Attachment of larger sub-unit of ribosome to the $mRNA-tRNA_{Met}$ complex.
(v) Linking of adjacent amino acids.
(vi) Formation of polypeptide chain.

• A. $(ii) \rightarrow (i) \rightarrow (iii) \rightarrow (v) \rightarrow (iv) \rightarrow (vi) $
• B. $(v) \rightarrow (ii) \rightarrow (i) \rightarrow (iii) \rightarrow (iv) \rightarrow (vi) $
• C. $(iii) \rightarrow (ii) \rightarrow (iv) \rightarrow (i) \rightarrow (v) \rightarrow (vi)$
• D. $(iii) \rightarrow (ii) \rightarrow (i) \rightarrow (iv) \rightarrow (v) \rightarrow (vi)$

Answer 1

Answer: (D)

Correct answer is (d) $(iii) \rightarrow (ii) \rightarrow (i) \rightarrow (iv) \rightarrow (v) \rightarrow (vi)$
