The diagram below represents the DNA sequence for a gene with three exons and two introns. Included are representations of the pre-mRNA, mature mRNA, and protein that are produced by the gene. Label the diagram to indicate the precise location of the sequence elements provided in the list below. a. The AG and GU dinucleotides corresponding to exon-intron junctions (place the AG and GU sequences in the correct positions on diagram). b. The +1 nucleotide (place a “+1” in the correct position on diagram). The 5′ UTR and the 3’UTR (place a “5′ UTR” and “3′ UTR” in the correct positions on diagram). d. The start codon sequence (place the start codon sequence in the correct position on diagram). e. A stop codon sequence (place a stop codon sequence in the correct position on diagram).
