Answer:
The correct answer will be option-C
Explanation:
Untranslated region or UTR is the regions of the mRNA which are not translated to proteins but plays an important role during translation.
The untranslated region is present on both the sides of the coding sequence that is at 5' end called 5' UTR or leader sequence and 3' UTR or trailer sequence.
The presence of 5' UTR is very important for transcription as the sequence of the UTR is recognized by the small subunit of the ribosome which allows the small subunit of the ribosome to initiate the process of translation.
Thus, Option-C is the correct answer.
