Answer:
<h2>
5' UTR E1 E2 E3 E4 UTR 3'</h2>
Explanation:
During RNA splicing, introns are removed and exons are joined tp each other to form a mature mRNA and this RNA moves to cytosol.. So 5' UTR , UTR 3' and all exons are joined together.
All introns are removed and exons are joind during RNA splicing process.
So the final mRNA is 5' UTR E1 E2 E3 E4 UTR 3'.
