Type: MCQ-conceptual-Medium-Class 12

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

Correct Answer

Option B

Detailed Explanation

Aminoacyl tRNA synthetase activates amino acids by adding ATP, which is essential for peptide bond formation during translation.
