Suppose That an Induced Mutation Removes Most of the 5

Multiple Choice

Suppose that an induced mutation removes most of the 5' end of the 5' UTR of an mRNA. What is most likely to happen?

A) Removal of the 5' UTR will have no effect because the exons are still maintained.
B) Removal of the 5' UTR also removes the 5' cap and the mRNA will quickly degrade.
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.
