87) For a the viral proteinsa. If the viral protein is made in the RER, it will go back to the nucleusb. IF they have nuclear localization sequence they will go to the nucleusc. The nuclear localization sequence can be either simple or bipartite of conserved leucined. If the viral protein is made by free ribosome, most likely it will go to the surface of the otthe cell.

Proteins are composed of amino acids, which are bound together by peptide linkage. Amino acids…

7 Why does incorporation of AZT into viral nucleic acids cause chain termination?
The first electron micrograph of a virus (tobacco mosaic virus) was produced in 1939. Before that time, how did scientists know that viruses existed if they could not see them? (Hint: Early scientists called viruses “filterable agents.”)
One of the first and most important targets for drugs to fight infection with HIV (a retrovirus) is the reverse transcriptase enzyme. Why?
(65) A new strain of influenza virus emerges that results in world wide pandemic of influenza. Affected persons lack pre-existing immunity to this strain. Which of the following genetic mechanism best explains the emergence of this pandemic strain? (A) Deletion (B) insertion (C) Point Mutation (D) Reassortment (E) Recombination
Explain the role receptor-mediated endocytosis (RME) plays in virus replication (lytic cycle). If you worked for a pharmaceutical company and wanted to develop a vaccine to prevent viral replication, how could you use your knowledge of RME to your advantage?

It is found that the affected guests stayed in rooms located in the east wing of the thrid floorof the hotel during a single3-week period. The causal virus most likely has which of the following chracteristics? (A) DNA genome (B) Helical symmetry (C) No envelope (D) No polymerase gene (E) Segmented genome
2. Bacteriophage are very specific in the types of cells they can infect. Some see this as a possible therapy to help treat against bacterial infections. Please discuss pros and cons of this type of therapy with proper support.
1. A particular virus with DNA as its genetic materialhas the following proportions of nucleotides: 20% A,35% T, 25% G, and 20% C. How can you explain thisresult?
3) The ACE2 receptor protein in humans has been getting a lot of press these days, as it apparently serves as a "receptor" for the SARS-CoV-2 coronavirus in addition to its normal functions. This protein has an isoelectric pH of 5.36. Suppose you want to purify this protein to study its properties, with the goal of developing a drug that would block it from binding the virus. Once you have purified the cell surface proteins from your cultured human lung cells away from all the other types of molecules in the cell, and all the cytoplasmic proteins, you might decide to use ion exchange chromatography to separate the ACE2 proteins from other proteins in your sample. If you plan to load your protein mixture onto your ion exchange column in a buffer at pH 7.4 (approximately physiological pH) and you want the ACE2 proteins to bind to the column, should you use a resin with a positive charge or a negative charge? Briefly explain why you chose the resin you selected.
1. Explain why it is NOT possible to treat diseases caused by prions with the same drugs that inhibit nucleic acid replication? 2. Explain how the attachment of viruses to bacterial cells is different from the attachment of viruses to animal cells.
