Summary Introduction
Introduction: HIV/AIDS stands for Human Immunodeficiency Virus/Acquired Immunodeficiency syndrome. This is an immunodeficiency disease that is caused by a class of retrovirus (the virus that has RNA genome and converts RNA to DNA). This disease lowers down the immunity of the body by attacking the helper-T cells and makes the individual prone to several infections.

The drugs used against HIV in AIDS therapy are not effective against the flu because

b. HIV is a DNA virus and influenza is an RNA virus.
c. the two viruses have different-sized genomes.
d. the proteins targeted by HIV drugs are not found in influenza.

The influenza virusa) is enveloped. b) is non-enveloped.c) has a DNA genome. d) has an RNA genome.e) causes a persistent infection.
Moderna and Pfizer vaccines for COVID-19 use mRNA to the Spike protein combined with lipids. Which of the following is/are advantages of this type of vaccine compared to an inactivated virus vaccine? Select ALL correct answers.
a) The vaccine is more stable for transport.
b) The vaccine does not contain the virus so it cannot give you COVID-19.
c) The vaccine can be rapidly produced in a slightly different form to protect from variants of SARS-CoV-2.

- An experimental drug therapy to treat patients with antibiotic-resistant bacteria involves introduction of a highly specific bacteriophage to the infected patient's bloodstream. Which of the following bacteriophage types would be the LEAST useful for this therapy? a. a lytic bacteriophage b. An enveloped virus c. An RNA virus d. a lysogenic bacteriophagearrow_forwardWhich of the following is a reason that scientists do not classify viruses as living things? A. They must infect a host because they cannot reproduce on their own. B. They contain DNA, like all living organisms. C. The experience evolution through natural selection. D. They replicate themselves and reproducearrow_forwardSome older vaccines used a weakened strain of the pathogenic virus in the injection in the hope that the weakened virus would induce an immune response without causing disease. The virus vectors used in genetic engineering have all the harmful virus genes cut out and replaced with the foreign gene, such as one that makes a protein that is absent in the human patient. Which type of viral vaccine would you prefer to take as the safest option? Why?arrow_forward
- Explain that a virus can’t be treated with an antibiotic and why. Think about selective toxicity and why those targets don’t exist for a viral infection.arrow_forwardYou are a scientist developing a vaccine against a newly discovered animal virus. What part of the virus would you target your vaccine against and why?arrow_forwardIf a virus particle contained double-stranded B-DNA of 500,000 base pairs, A. How many complete helical turns would occur on each strand? B. How many atoms of phosphorus would be present? C. What would be the length (in Å) of the DNA before packing into the virus?arrow_forward
- Viruses: a. Describe the structure and composition of viruses. What are three reasons that they are different from cellular organisms? b. Describe what a lysogenic bacteriophage is and how it is different from a lytic bacteriophage. c. Describe what is similar and different about the lifecycle of a non-enveloped DNA animal virus compared to an enveloped animal retrovirus.arrow_forwardTo infect their specific host cells, viruses go through these chronological steps EXCEPT a. Release of progeny viruses b. Absorption and penetration of the viral particles c. Uncoating of the nucleic acid of the viral particles d. Synthesis and assembly of viral particle componentsarrow_forwardSome older vaccines used a weakened strain of the pathogenic virus in the injection in the hope that the weakened virus would induce an immune response without causing disease. The virus vectors used in genetic engineering have all the harmful virus genes cut out and replaced with the foreign gene, such as one that makes a protein that is absent in the human patient. Which type of viral vaccine would you prefer to take as the safest option? Why? Some Covid 19 vaccines in development use the adenovirus, a common vector used in gene therapies, to inject the mRNa for the spike protein into human muscle cells. Why might vaccines using a virus vector be more likely to need only refrigeration and not deep-cold storage, given what you know about viruses?arrow_forward
- A" is a retrovirus. It can integrate DNA into random sites of human genome. Another virus "B" can integrate DNA at a specific site of human genome. Which one of these viruses would make a better vector for gene therapy? Briefly explain.arrow_forwardWhich of the following statements concerning viruses and human health is false? a-in many diseases caused by viruses, the virus attacks cells as it reproduces b- many viral diseases can be controlled through vaccinations c- some viruses can remain dormant in the body for years before disease symptoms appear d-most viral infections are difficult to treat, but they can be finally destroyed by antibioticsarrow_forwardWhy is the Nipah virus a great illustration of a zoonotic disease? A. Because it's carried by fruit bats across America but it's not even noticed by the American people. B. Because it's carried by cats across Asia and easily spills over into humans. C. Because it's carried by fruit bats across Asia but almost never spills over into humans. D. Because it's carried by fruit bats across Asia and easily spills over into humans.arrow_forward
