QUESTION 2 The SARS-COV-2 pandemic resulted in the desire to design ELISA assays to either detect antibodies against SARS-CoV-2 protein (previous infection), or detect viral protein (current infection). You plan to express the mutant spike protein variant using the plasmid pictured below as your template. Here's the sequence you want to put in its place: https://www.ncbi.nlm.nih.gov/nuccore/AY429073.1?report=fasta, this is the DNA sequence you're going to buy as a gene block! But you need to add a couple things to it first so it'll get into the plasmid. To do so, you're going to need to remove the current insert (represented by the yellow arrow beginning at position 833-4867). Question: What restriction sites are you going to add at the ends of the gene? Answer can be in nucleotides or the enzyme name. For the first blank fill in the site name/sequence you'd add at the beginning of the gene (5' / C-terminus end) and for the second blank fill in the sequence/site name you'd add at the…

Question 1 options: The specificity pocket of the serine protease chymotrypsin, which interacts with Tyr and Phe-containing peptide sequences, contains a Ser residue. A research group is trying to modify chymotrypsin such that it has a low KM with Trp-containing peptides. Enter the name or abbreviation of an amino acid that the Ser could be mutated to that would likely have the desired effect. (Hint: look at the diagrams of the specificity pockets shown in the course slides, and consider how the Ser would need to change to account for the difference between Tyr/Phe and Trp.)

QUESTION 14 Which of the following statements about bacterial translation is FALSE? O A. The arrangement of key sites within the ribosome is in the order E, P, A, for exit, peptidyl, and aminoacyl O B. Steps in translation initiation, elongation, and termination are moved forward in an irreversible mechanical process, almost like turning a crank, that relies on the hydrolysis and exchange of GTP. O C. The first step in translation is the binding of the 30S RNA subunit to the Shine Delgarno sequence, together with IF-1 and IF-3. O D. Termination of translation requires a set of release factors RF1/2, RF3, and RRF which help coordinate events following the recognition of a stop codon by one of the three stop codon tRNAS O E. A polysome consists of multiple ribosomes reading the same MRNA at once. Those positioned towards the end of the mRNA have translated more of the protein than the ribosomes positioned at the beginning.
