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!!
