Solved in 3 steps
- 1. Why the virus was not found in the tests? 2. Why the treatments are not working?1. a.Upon looking at these pictures, what are your thoughts regarding this pandemic that we are facing right now? Do you believe that this corona virus serves as a Chinese weapon to fight against their enemy or it is just an accident? 1.b.Is COVID-1 virus 9 a living thing or a non-living thing?During viral gene therapy (using the adenovirus system), does the new DNA that you introduce into cells get incorporated into the organisms genome? O Yes O No
- The discovery of HIV virus was a race between two groups of scientists. Do you think the scientistic research should be a “race”? What are the pros and cons of such a race?1. TRUE OR FALSE:There is strong evidence that the "seeds" for life in this planet might have come from outer space, since evidence for complex organic molecules (e.g. amino acids) has been discovered in meteorites and in outer space. 2. TRUE OR FALSE: Kuru is caused by a neurotropic virus that "homes" or looks for the brain cells. This virus belongs to the same family of viruses that cause mad cow disease, and it is one of the smallest "life forms" in planet earth. 3. TRUE OR FALSE: Over 150 complex organic molecules have been identified in deep space; some of these resemble amino acids. The study suggest that all three environments; outer [deep] space, meteorites and the surface of a planet may all very well lent a hand in the development of life. 4. TRUE OR FALSE: One of the limitations of the current fossil record in our planet is that it is biased in favor of the species that have left hard bony structures and/or had lived for long periods of time. 5. TRUE OR FALSE: To date, we…A virus broke out in a remote area. There are no infected people in my area yet. But we have lots of samples. Please explain in detail how we got a lot of samples.
- The virion illustrated below is a O Bacteriophage O poxvirus O HIV retrovirus O Adenovirus3. Someone in your office has the flu. How would the social habits of your office cause other people to catch the virus? Can you think of a way to prevent the influenza virus from spreading (that will not hurt anyone's feelings)? 4. The symptoms of many viruses come and go within 24 h. Use viral replication information to explain why this is the case. FEB étv %24 % 7 9. 4 R T Y F G K C V M MOSISO com V *00 5You have a discussion among friends about viruses that can cause latent and chronic infections in humans. The first friend says that an example for latent infections in humans are oral and genital herpes caused by herpes simplex virus and that examples of viruses causing chronic infections are Hepatitis C and HIV. The second friend says oral and genital herpes as well as chickenpox/ shingles are chronic infections and that HIV is an example for a virus causing a latent infection.

- You discovered a novel virus causing a new disease. Briefly describe how will you go about characterizing it to prove that it is indeed a novel virus.4. Each year in late winter a behavioral “disorder" engulfs the people of New Orleans, Louisiana, reaching a climax on the day before Ash Wednesday. Together with virologists at Louisiana State University, you have isolated a virus from the affected people that you suspect is responsible for this condition. You have named the new isolate Mardi Gras virus (MGV). You have found a convenient host cell in which to grow MGV in the laboratory. The following table lists some of the properties of MGV Initial Data for Mardi Gras Virus you have discovered. Experiment Observation Physical nature of the virion Electron microscopy (EM) reveals 100-nm particles; shape indicates presence of envelope with visible surface projections; ether destroys particle integrity. Chemical nature Digested with RNase; degraded by of viral genome alkali; resistant to DNase. Informational nature of viral Genome cannot be translated in cell- free protein synthetic system. genome With NTP precursors: catalyzes RNA…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?
