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.)

This is a homework question that I have on my Adv. Anatomy & Physiology assignment. How to I got about answering the question? (I do have the Codon table in my textbook) Consider a hypothetical protein that consists of the amino acid sequence arginine, phenylalanine and histidine. From this information, construct (1) the original DNA strand, (2) corresponding mRNA codons and (3) tRNA anticodons used to produce this hypothetical protein. (Only use 1 mRNA codon per amino acid.) In addition, be sure to include start and stop sequences where appropriate.
