Question

Which of the following statements is correct regarding eukaryotic translation?

(a) mRNA attaches itself to larger subunit of ribosome in the region of its cap for initiation.

(b) Aminoacyl tRNA synthetase activates the amino acids by adding ATP that is later used in formation of peptide bond.

(c) During aminoacylation of tRNA, the amino acid gets linked to 5' -COOH group of tRNA through its 3' OH group.

(d) During elongation of polypeptide chain the aminoacyl tRNA complex reaches at E-site and attaches to mRNA codon next to initiation codon.

Answer 1

Correct option (b) Aminoacyl tRNA synthetase activates the amino acids by adding ATP that is later used in the formation of peptide bond.

Explanation :

Aminoacyl tRNA synthetase helps in combining amino acid to its particular tRNA by adding AIP that is later used in the formation of a peptide bond.
