Question:

Read the passage and answer the following questions :
Translation refers to the process of polymerisation of amino acids to form a polypeptide. The order and sequence of amino acids are defined by the sequence of bases in the mRNA. The amino acids are joined by a bond which is known as a peptide bond. Formation of a peptide bond requires energy.

Which among the following bond helps in the joining of amino acids ?

Options:

Phosphodiester bond .

Peptide bond .

Hydrogen bond .

Covalent bond .

Correct Answer:

Peptide bond .

Explanation:

The correct answer is Option (2) -Peptide bond .

The bond that helps in the joining of amino acids to form a protein chain is called the "Peptide bond."

A peptide bond is a specific type of covalent bond that forms between the carboxyl group (-COOH) of one amino acid and the amino group (-NH2) of another amino acid during the process of protein synthesis. This bond formation occurs through a dehydration synthesis reaction, resulting in the elimination of a water molecule and the linkage of the two amino acids.
