In the virus image below, what is the likely function of the projections seen on the virus particle? They contain the virion's genetic information.   They prevent the virion from being recognized by the host.   They contain the enzymes that replicate the virus particle.   They facilitate attachment of the virion to the host cell.

Can Cytomegalovirus (CMV) release any toxicant? What I mean is if the virus perform any kind of chemical rection while inactive like when it is in the environment releasing toxins or when is active inside the host such as inside the human body?

Compare how retroviruses solve the problem of replicating an RNA genome in a eukaryotic host with how other types of RNA viruses solve this same problem.

Which of the following statements is true regarding the M13 virus coat protein? (Refer to the figure) 9 Positive R, K, H Negative D, E 5 10 15 20 25 30 35 40 45 50 The amino acids in the beginning of the chain should face the DNA. The amino acids towards the higher number end of the chain should face the DNA. The amino acids at the higher end of the chain can destabilize the DNA. The amino acids at the beginning of the chain can stabilize the DNA.

Viruses are made up of the same biomolecules as cellular organisms (DNA, RNA, proteins, lipids, etc.), which are synthesized through enzymatic dehydration reactions from building blocks and disassembled by enzymatic hydrolysis. They infect cells and replicate themselves using resources from the host cells. Scientists discovered a previously unknown strain of virus in the tropical Pacific Ocean and it can infect higher-order eukaryotes. Initial analysis revealed that the virus is mainly composed of nucleic acids, proteins, and lipids. Chemical analysis after complete hydrolysis revealed the following building blocks (by weight): Chemical components Nucleosides Amino acids Lipids, phosphates, and carbohydrates Percentage by weight 20 30 50 Analysis of percentages of nucleosides yielded the following results (by molar ratio): Nucleosides A G T C U Percentage by mole 19 29 19 29 4 Which of the following events mostly involves hydrolysis reaction after the virus infects…

Can you pick a virus and describe the  structure and metabolism of the virus.  For the virus, describe the metabolism of the host cell.

Some viruses such as HPV are linked to mutations causing certain types of cancer. What part of a virus life cycle can add mutations to host DNA?       What type of bacteriophage, as defined by life cycle, could do this?

Please briefly state the importance of each stage of viral replication. Do not just restate what each stage does. In addition, why must a virus infect a cell to survive and reproduce?

What defines a virus' host range? Know the multiplication steps (in order) for a virus (both bacteriophage and animal viruses). What happens at each step? What is the major difference between the steps in animal viruses vs. bacteriophages? Describe the lytic and lysogenic cycles of bacteriophage infection. What are the different types of viral genomes possible? What are the differences between entry and exit for enveloped vs naked viruses? o i.e. fusion, endocytosis, budding or exocytosis, lysis/bursting/rupturing, Explain how viruses are cultured. Why would viruses need to be cultured? What is a latent viral infection? What are cytopathic effects (know examples). Know characteristics of viroids and prions. What are they? What kinds of diseases can they cause (know examples for prions) How can viral infections be treated? bp

A (+) Sense virus makes a negative sense copy of its genome. Part of the (+) Sense genome has the sequence: 3'-GUGGCAGUA-5'. What is the sequence of the (-) sense copy? O 5'-AUGACGGUG-3' O 5' - CACCGUCAU - 3' O 3'-AUGACGGUG-5' O 5' - UACUGCCAC - 3'
