| 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) ? |
5' end 3' end Both 5' and 3' end Either 3' or 5' end |
| Both 5' and 3' end |
| 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. |
