Question

Select an option that shows the correct sequence of the events involved in the translation mechanism.
a. Binding of mRNA to a smaller subunit of ribosome
b. Aminoacylation of tRNA
c. Binding of initiator tRNA to the P-site of the ribosome
d. Formation of polypeptide
e. Formation of a peptide bond between first and second amino acids at the A site

• A. $a\to b\to c\to d\to e$
• B. $b\to a\to e\to c\to d$
• C. $b\to d\to a\to c\to e$
• D. $b\to a\to c\to e\to d$

Answer 1

The correct option is D $b\to a\to c\to e\to d$

The events are arranged in the following order:-

Aminoacylation of tRNA → Binding of mRNA to a smaller subunit of ribosome → Binding of initiator tRNA to the P-site of the ribosome → Formation of a peptide bond between first and second amino acids at the A site → Formation of polypeptide.

So, the correct option is 'b→a→c→e→d'.
