Viral Life Cycle and Host Interaction Quiz

#1

Which step of the viral life cycle involves the injection of viral genetic material into the host cell?

Penetration
Explanation

Penetration: Viral genetic material enters the host cell.

#2

Which of the following is NOT a method by which viruses can enter host cells?

Replication
Explanation

Replication: Not a mechanism for virus entry into host cells.

#3

Which step of the viral life cycle involves the release of newly assembled viral particles from the host cell?

Release
Explanation

Release: Newly assembled viral particles exit host cell.

#4

What is the main function of the viral protein coat (capsid)?

Protect viral genetic material
Explanation

Capsid: Protects viral genetic material.

#5

Which stage of the viral life cycle involves the synthesis of viral components using host cell machinery?

Replication
Explanation

Replication: Viral components synthesized using host machinery.

#6

During which stage of the viral life cycle are new viral particles assembled from replicated genetic material and viral proteins?

Assembly
Explanation

Assembly: New viral particles are put together.

#7

Which type of virus is known for integrating its genetic material into the host cell's DNA?

Retrovirus
Explanation

Retrovirus: Integrates genetic material into host cell DNA.

#8

What is the role of the viral enzyme reverse transcriptase?

To replicate viral RNA into DNA
Explanation

Reverse transcriptase: Converts viral RNA to DNA.

#9

Which of the following is a primary receptor used by HIV to enter target cells?

CD4
Explanation

CD4: Primary receptor for HIV entry into cells.

#10

What is the role of neuraminidase in the life cycle of influenza virus?

To release newly formed virus particles from the host cell
Explanation

Neuraminidase: Facilitates release of influenza virus particles.

#11

Which of the following is NOT a mechanism by which viruses evade the host immune system?

Apoptosis
Explanation

Apoptosis: Not a mechanism for evading the immune system.

#12

Which of the following is a strategy used by viruses to enter host cells without being detected by the immune system?

Camouflage
Explanation

Camouflage: Strategy for evading immune detection.

#13

Which of the following is a viral protein that interferes with host cell signaling to promote viral replication?

Viral kinase
Explanation

Viral kinase: Interferes with host cell signaling for replication.

#14

Which of the following is a viral protein that helps viruses evade the host immune response by inhibiting interferon production?

Viral kinase
Explanation

Viral kinase: Inhibits interferon production for immune evasion.
