Viral Infections

Viruses are abundantly found, minute entities that have genetic material enclosed within a protein coat. The proteinaceous material enclosing the genetic material of the virus is called a capsid. The genetic material could be either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). A virus is too minute to be looked at with naked eyes and therefore visualized with the help of a microscope. They are acellular entities that require a host for processes, such as replication, transcription, translation and multiplication. Plants, animals, and bacteria act as host wherein the virus reproduce. Viruses cannot multiply outside the host's body and thus are considered nonliving outside the host body.

Question

Most viral infections, including the common cold, chickenpox, mononucleosis and Ebola, are untreatable. Few antiviral drugs exist, and those in use may cause severe side effects to the patient. Why are viral infections so difficult to treat? Why do you think antiviral drugs cause severe side effects? Are there steps in viral reproduction that new antiviral medications could target?

Which of the following happens to the viral nucleic acid during a lysogenic cycle cycle? a-the viral DNA immediately takes over the host cell genetic material b-it bursts the host cell c-the viral DNA forms a provirus d-the viral DNA is used to attach the bacteriophage to the host cell`s receptors
What is true about the difference between prions and viruses? Viruses have genomes composed of RNA, whereas prions have genomes composed of DNA. Viruses have capsids composed of protein, whereas prions are made only of nucleic acid. Viruses infect many types of cells, whereas prions infect only prokaryotic cells. Viruses generally cause disease symptoms quickly, whereas prions generally take many years to cause disease symptoms.
In 2006, the US Food and Drug Administration (FDA) approved the use of bacteriophage preparation that can be used on ready-to-eat meat and poultry products to kill Listeria monocytogenes, a bacterium that causes listeriosis. Some people may have concerns about the use of phages in foods. From what you have learned about bacteriophages and viruses, why do you think we do not have to be concerned about the presence of bacteriophages in food?
Which of the following statements seemingly refute the fact that viruses are nonliving? A.They reproduce themselves only inside a host cell. B. They contain no enzymes. C. They can change over time, with the emergence of new strains. D. They cause diseases similar to those caused by bacteria. E. They are composed of protein and nucleic acid.
Arrange the following list into the correct sequence for part of the cycle of a retrovirus: 1. dsDNA integrated into host DNA 2.viral proteins synthesized on host ribosomes 3. viral DNA uses host enzymes to transcribe viral RNA 4. reverse transcriptase catalyzes synthesis of ssDNA 5. synthesis of second DNA strand (a) 5, 2, 1, 3, 4 (b) 5, 2, 3, 4, 1 (c) 4, 5, 1, 3, 2 (d) 4, 1, 2, 3, 5 (e) 2, 1, 3, 4, 5
Coronaviridae is a virus “family.” There are actually many different coronaviruses within this group, including less pathogenic virus strains that cause the common cold. Many people in this course have likely been infected with one of these other coronaviruses. A common feature of coronaviruses and other RNA viruses (think influenza virus, HIV, etc.) is that they mutate frequently. This is because the viral enzymes that copy the genome during replication can’t fix mistakes. Given this information, how might we be able to distinguish the SARS-CoV-2 strain from some of the other, less concerning, coronavirus strains?
Will it be possible to eradicate many viral diseases in the same way as smallpox? Why or why not?
As a general rule, viruses are not considered to be alive based on several reasons. One such reason is that some viruses use RNA as their genetic material instead of DNA. Which of the five biological themes does this violate? Briefly explain why.
The Ebola virus is an enveloped, helical ssRNA virus that replicates quickly. Given this information, which one of the following is a reason why Ebola infection is difficult to fight (both by our bodies and by treatments)? Question 6 options: Because it has many genes and thus replication is slow. Because it doesn't have a membrane. Because viral RNA polymerases make a lot of mistakes. Because it can integrate into the host cell DNA. Previous PageNext Page
