Use the Following Model of a Eukaryotic Transcript to Answer

question 28

Multiple Choice

Use the following model of a eukaryotic transcript to answer the question.E_1-4 refer to the exons,and I_1-3 refer to the introns in the pre-mRNA transcript.
5' UTR E₁ I₁ E₂ I₂ E₃ I₃ E₄ UTR 3'
Suppose that an induced mutation removes most of the 5' end of the 5' UTR.What might be the result of this removal?

• A)Removal of the 5' UTR has no effect because the exons remain intact.
• B)Removal of the 5' UTR also removes the 5' cap,so the mRNA may be quickly degraded by hydrolytic enzymes.
• C)The 3' UTR will duplicate,and one copy will replace the 5' end.
• D)The first exon will not be read because I₁ will now serve as the UTR.
