Question : Why are some untranslated sequences of bases seen in mRNA coding for a polypeptide? Where exactly are they present on mRNA?

 

The correct answer is – The untranslated regions are required for an efficient translation process. hey are present before the initiation codon at the 5’ – end and after the stop/termination codon, at the 3’ – end
