Homework Answers
Option c is the correct answer. The 3' UTR (3' untranslated region) is found immediately after the termination (stop) codon in mRNA. Here the nucleotide sequence just before the 63rd nucleotide is TAA. THis TAA will become UAA in mRNA because in RNA, uracil is present instead of thymine in DNA. UAA is stop codon (as shown in table) and thus, Just after the TAA sequence that is from 63rd nucleotide The 3'UTR region begins. Hence the correct answer is c.
