BIOD 171 Module 6 Exam Review – Practice Questions
& Answers | 2026 | Graded A+
1. "Which enzyme of influenzavirus is targeted by drugs such as Tamiflu,
Oseltamivir, or Zanamivir to prevent release of the virus from infected cells?"
neuraminidase
Flagellin integrase
hemagglutinin
2. Which of the following is/are true about Rubella:
It is caused by a herpes virus
The rash is generally vesicular
The infectious period is from one week before symptoms to 4 days after the
onset of rash
Clinical diagnosis is usually reliable
The incubation period is 10-12 days
3. What virus is responsible for invading motor neurons in the brain or spinal cord,
causing paralysis?
Poliomyelitis
Mumps
Measles
Rubella
,4. Describe the role of the tail fibers in a bacteriophage's structure.
The tail fibers protect the genetic material.
The tail fibers help the bacteriophage attach to the host cell.
The tail fibers are involved in the assembly of the virus.
The tail fibers assist in the replication of the virus.
5. Describe the relationship between German measles and conjunctivitis.
Conjunctivitis is a primary cause of German measles.
Conjunctivitis only occurs after German measles is resolved.
German measles and conjunctivitis are unrelated diseases.
German measles can cause conjunctivitis as a symptom during the infection.
6. What is the final step of the viral replication cycle, where new viral particles are
released from the host cell?
Release
Replication
Entry
Attachment
7. ______ (measles) is transmitted through small particle residue and can be suspended
in air, requiring airborne precautions
, Ebola
Rubeola
C. difficile
Rubella
8. Describe the significance of the protein p24 in the structure of the HIV viral capsid.
The protein p24 is a major component of the HIV capsid, contributing to its
structural integrity and is present in approximately 2,000 copies.
The protein p24 is involved in the viral replication process and is found in low
quantities.
The protein p24 is a receptor on the host cell that HIV binds to.
The protein p24 is responsible for the transmission of HIV between
individuals.
9. If a new strain of Influenza A emerges, what implications might this have for public
health and vaccination strategies?
It would lead to an immediate eradication of the virus.
It would only affect individuals who have previously been vaccinated.
It would have no impact on public health as all strains are treated the same.
It may require the development of new vaccines and public health measures to
control its spread.
10. If a patient presents with localized blisters on one side of their torso, which viral
infection are they most likely experiencing, and why?
, Chickenpox, because it causes blisters all over the body.
Measles, because it causes a rash that includes blisters.
Shingles, because it typically causes localized blisters in specific dermatomes.
Herpes simplex, because it causes blisters around the mouth.
11. If a new virus is discovered that is larger than Smallpox virus but smaller than
Paramyxovirus, how would you categorize its size relative to the known viruses?
It would be categorized as larger than Poliovirus but smaller than Smallpox
virus.
It would be categorized as equal in size to Paramyxovirus.
It would be categorized as the largest virus known.
It would be categorized as smaller than all three known viruses.
12. Describe the structural differences between animal viruses and plant or bacteria-
infecting viruses.
Animal viruses are predominantly enveloped, while plant and bacteria-
infecting viruses are mostly non-enveloped.
Plant viruses have more complex structures than animal viruses.
Animal viruses have a rigid structure, while plant viruses are flexible.
Bacteria-infecting viruses do not have any structural components.
13. Herpes zoster ("shingles") generally present during
