Question

A: UTRs are found on mRNA which do not play direct role in coding of aminoacids during translation R: UTRs are nonsense codons.​

Answer 1

Explanation:

Untranslated regions of mRNAs

Flavio Mignone, Carmela Gissi

Abstract

Gene expression is finely regulated at the post-transcriptional level. Features of the untranslated regions of mRNAs that control their translation, degradation and localization include stem-loop structures, upstream initiation codons and open reading frames, internal ribosome entry sites and various cis-acting elements that are bound by RNA-binding proteins.
