Chapter 9, Problem 33P

Diagram a eukaryotic gene containing three exons and two introns, the $\text{pre-mRNA}$ and mature $\text{mRNA}$ transcript of the gene, and a partial polypeptide that contains the following sequences and features. Carefully align the nucleic acids, and locate each sequence or feature on the appropriate molecule.

the $\text{AG}$ and $\text{GU}$ dinucleotides corresponding to intron-exon junctions

the $\text{+1}$ nucleotide

the $\text{5' UTR}$ and the $\text{3' UTR}$

the start codon sequence

a stop codon sequence

a codon sequence for the amino acids $\text{Gly-His-Arg}$ at the end of exon $\text{1}$ and a codon sequence for the amino acids $\text{Leu-Trp-Ala}$ at the beginning of exon $\text{2}$.
