Texts: 1. Perform NCBI Protein searches to answer these questions (2 pts): a. Are there more sheep (Ovis aries) or mouse (Mus musculus) protein sequences in the RefSeq database? How many of each type are there? b. Identify the longest human protein in the RefSeq database. Give its accession number and length (in amino acids), and provide the accession number of the related mRNA sequence. Also, in one sentence, describe the protein’s function.

Question 1. For the following questions, use the genetic code in table 18.1. A DNA strand consists of 3'-TCAATACCCGCG-5'. What is the nucleotide order of the complimentary mRNA? What sequence of amino acids is coded by the DNA? Question 2. Which mutation do you think would be more serious? Why? AUG to AUC or AUC to AUA? CAU to CAA or CUU to AUU? UUU to UUUU or UUU to UUA? UGU to UGC or UGU to UGA?

Match each major class of protein with the best representative protein from each class. Question 1 options: Aquaporin Actin Adenylate cyclase Histone Pepsin 1. Structural proteins 2. Genomic caretaker proteins 3. Metabolic enzymes 4. Transport proteins 5. Cell signaling proteins Predict the fragments of the following peptide after cleavage by trypsin. DASRTYPECHI Question 2 options: A.) DASR TYPECHI B.) DASRTYPE CHI C.) DASRTY PECHI D.) DAS RTYPECHI 3. Which of the TWO following statements about x-ray crystallography are true? Question 3 options: All atoms scatter x-rays equally. X-ray crystallography is the only technique which can determine the three-dimensional structure of a protein. The basic experimental data are relative intensities and positions of scattered electrons. Only crystallized proteins can be analyzed. The x-ray beam is scattered by the protein sample.
