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 part of mRNA contains untranslated regions (UTR) ?
Answer & explanation
Correct answer: option 3
An mRNA also has some additional sequences that are not translated
and are referred as untranslated regions (UTR). The UTRs are present
at both 5' -end (before start codon) and at 3' -end (after stop codon). They
are required for efficient translation process.
