1. Diagram a eukaryotic gene containing three exons and two introns. Your diagram should show DNA and the mature mRNA molecules. Show the following (if it exists in the DNA indicate so, if it exists in the mature mRNA, indicate so): a. AG and GU dinucleotides corresponding to intron-exon junctions b. +1 TSS C. 5' and 3' UTRS d. the start codon sequence e. the stop codon sequence f. the...

Below is the DNA sequence of a protein-encoding Eukaryotic gene: 5’TAAACGCGATGGACCGACCATACAGTATCGACGCTCCAGGATGGTAAAATAAATGCCT3’ Based on this information, predict the mature mRNA sequence and the corresponding peptide sequence of this gene after transcription, RNA processing, and translation. Try to recognize and label the sequence features on the primary transcript you learned from the class that are important for Eukaryotic mRNA Processing (e.g. intron sites, poly-A adding site). Please also briefly describe the key steps taking place during RNA processing. For each step of...

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!!
