A drug company is trying to develop a new drug that will inhibit the release of newly
produced viral particles. Would the drug company target hemagglutinin proteins or
neuraminidase proteins? Why? - CORRECT ANSWER: Neuraminidase proteins are
directly involved in the budding and release of new viral particles and would be the
correct target. Hemagglutinin proteins would not be advisable targets bc they are
directly involved in viral attachment and entry into the host cell.
A drug company is trying to develop a new drug that will inhibit viral entry of Influenza.
Would the drug company target hemagglutinin proteins or neuraminidase proteins?
Why? - CORRECT ANSWER: Hemagglutinin proteins would be targets because they
are directly involved in viral attachment and entry into the host cell. Neuraminidase
proteins are involved in the budding and release of new viral particles so they wouldn't
be the right target.
A patient diagnosed with German measles may additionally experience what disease?
Select all that apply.
- Impetigo
- Conjunctivitis
- Rheumatic fever
- Infleunza-like symptoms - CORRECT ANSWER: - Conjunctivitis
- Influenza-like symptoms
A person who has neither previously had chickenpox nor been administered the VZV
vaccine is exposed to someone with an active VZV (shingles) outbreak and becomes
infected. Explain why (or why not) the person will only develop shingles. - CORRECT
ANSWER: The person won't develop shingles, but will develop chickenpox.
, Unvaccinated and unexposed individuals have to develop chickenpox first because
shingles is the reactivation of the dormant VZV virus from the chickenpox infection.
A virus that infects bacteria is called a [answer1] and contains a [answer2] -sided
polygon capsid. - CORRECT ANSWER: 1. Bacteriophage
2. 20
An individual infected with HIV is placed on anti-retroviral medication. What is the
general purpose of this medication? - CORRECT ANSWER: the general purpose of
anti-retroviral is to block the production of new viruses by
preventing its integration and replication.
Based on the following image, would you expect the viral titer to be high or low? Why? -
CORRECT ANSWER: Low, since the amount of intact bacterial cells in the media
determines its turbidity,
the amount of virus present in the tube has to be minimal. The amount of virus in the
image is low. As the lytic cycle continues, more bacteria cells will be destroyed and the
media will be cleared.
Describe the main differences between lytic and temperate phages. - CORRECT
ANSWER: - Lytic bacteriophages replicate within the host bacteria until it ruptures.
- Temporate phages primarily exist in a non-replicating state that does not kill the host
cell.
Describe the main underlining differences between the Salk and Sabin polio vaccine. -
CORRECT ANSWER: The Salk vaccine contained an inactivated form of the virus and
was injected. The Sabin vaccine contained a live but weakened form of the virus and
was administered orally.
Describe the two basic components of a virus. - CORRECT ANSWER: A virus has
genomic material made up of either DNA or RNA and a capsid which is a protective
structure that contains genetic material
