Q23: Dr. Alghe has just performed a restriction digest on DNA she extracted from her samples. She must now run her DNA out on a gel to separate the fragments based on size. To do this she must prepare a 1.1% agarose gel, where the percentage is determined as mass/vol. How many grams of agarose must she add to 413 mL of buffer in order to arrive at the correct percentage? (answer to 2 decimals) **Assume the dissolution of agarose will not alter the final volume of the solution**

4) Paxlovid is treatment for COVID-19 that was recently approved for use because it can drastically reduce the risk for hospitalization and death when taken early in the infection. It is actually a package of two different antiviral drugs. One of those is Nirmatrelvir, which is a modified tripeptide protein mimetic designed to covalently bind to and inhibit the main protease (MPro) from the SARS-CoV-2 virus. This protease recognizes and hydrolyzes peptide bonds at specific points in their sequence, and it is essential for viral replication. a. Below is one of the sequences that Mpro recognizes and cleaves. It cleaves the peptide bond between the glutamine and the glycine. Draw out the structure of a peptide with this sequence, including the appropriate stereochemistry for biological amino acids and assuming the peptide is at physiological pH (pH = 7.4). SGVTFQGKF b. What would the net charge of the peptide be at physiological pH?. c. At what pH would the peptide be net neutral?

The interaction of many different protein factors to stimulate or repress transcription forms a complex called: combinatorial control synergy ALL OF THESE mediator. NONE OF THESE
