Question

Where are the untranslated regions (UTRs) present?

(a) At both the 5’ and the 3’ ends

(b) At only the 5’ end

(c) At only the 3’ end

(d) Outer to the 5’ and the 3’ end

I have been asked this question by my college professor while I was bunking the class.

My question comes from Molecular Basis of Inheritance topic in chapter Molecular Basis of Inheritance of Biology – Class 12

Answer 1

Correct option is (a) At both the 5’ and the 3’ ends

To explain I would say: The untranslated regions (UTRs) are the additional sequences of the mRNA which aren’t translated during the process of translation into proteins. This region is present at both the 5’ and the 3’ end. They are required so that an efficient process of translation occurs.
