Define the different elements comprising a eukaryotic “gene body," whether or not copies of these different elements are present in mature mRNA, and whether or not they code for protein. If you can include a photo with labels and include the terms transcriptional start site, 5' untranslated region (UTR), start codon, intron, exon, stop codon, and 3' untranslated region, that'd be great!!

Hemoglobin is a protein that is found in red blood cells. It binds to oxygen in the lungs and it carries it to tissues and cells throughout the body. Hemoglobin is made of four polypeptide chains, two called “alpha-globins” (a) and two “beta-globins" (B). The B-globin polypeptide is produced in the cells based on the sequence of the HBB gene. The structure of the HBB gene that codes for beta-globin is represented below. The primary transcript is 1606 nucleotides long....
