Question

Read the following and answer from given below:

The translation is the process of polymerization of amino acids to form a polypeptide. The order and sequence of amino acids are defined by the sequence bases in the mRNA. The amino acids are joined by a bond called a peptide bond. The ribosome is the site of protein synthesis.

Which part of mRNA contains untranslated regions (UTR)?

पर्याय

• 3' end

• 5' end

• Either 3' or 5' end

• Both 5' end and 3' end

Answer 1

Both 5' end and 3' end

Explanation:

An mRNA molecule has some additional sequences that are not translated and are called untranslated regions (UTR). The UTRs are present at both 5' end (before start Condon) and at 3'-end (after stop codon). They are required for an efficient translation process.
