Use this model of a eukaryotic transcript to answer the following question.
E = exon and I = intron
5′-UTR E₁ I₁ E₂ I₂ E₃ I₃ E₄ UTR-3′
Which components of the previous molecule will also be found in mRNA in the cytosol?
A) 5′-UTR I₁ I₂ I₃ UTR-3′
B) 5′-E₁ E₂ E₃ E₄-3′
C) 5′-UTR E₁ E₂ E₃ E₄ UTR-3′
D) 5′-E₁ I₁ E₂ I₂ E₃ I₃ E₄-3′

In eukaryotic cells, the mRNA in the cytosol is processed to remove introns, leaving only exons and untranslated regions (UTRs). Thus, the mRNA will contain the 5′-UTR, all exons (E₁, E₂, E₃, E₄), and the 3′-UTR.
