lytic and lysogenic Virus Replication Quiz

What is the first step in the lytic and lysogenic virus replication process?

• Integration of viral DNA into the host genome

• Assembly of new viral particles within the host cell

• Release of genetic material into the host cell

• Attachment to the host cell

Explain how a virus attaches to a host cell.

• Entering the cell through the process of photosynthesis

• Attaching to the cell's nucleus

• Penetrating the cell membrane through osmosis

• Binding to specific receptor molecules on the surface of the cell

How does a virus inject its genetic material into a host cell?

• By releasing toxins into the host cell

• By physically inserting its genetic material into the host cell with a needle-like structure

• By using its tail to inject the genetic material into the host cell

• Using specialized proteins on its surface to bind to receptors on the host cell membrane

Describe the process of viral genetic material replication within a host cell.

• Virus attaches to host cell, releases genetic material, replicates using host cell's machinery, assembles new viral particles, and releases them to infect other cells.

• Virus replicates using host cell's machinery, assembles new bacterial particles, and releases them to infect other cells.

• Virus attaches to host cell, releases genetic material, and then self-destructs.

• Virus releases genetic material, attaches to host cell, and replicates using its own machinery.

What happens during the release of new viral particles from a host cell?

• Mature viral particles are released from the host cell

• The viral particles are destroyed within the host cell

• The host cell divides into two new cells

• The host cell absorbs the viral particles

Explain the integration of viral DNA into the host genome.

• The viral DNA is incorporated into the host genome by the host's immune system.

• The viral DNA is inserted into the host genome by the viral integrase enzyme.

• The viral DNA is absorbed by the host genome through osmosis.

• The viral DNA is attached to the host genome by the viral capsid.

What is the final step in the lytic and lysogenic virus replication process?

• Activation of the host immune response

• Release of new virus particles from the host cell

• Integration of viral DNA into the host genome

• Destruction of the host cell

How does a virus release new viral particles from a host cell?

• By using the host cell's machinery to replicate its genetic material and assemble new viral particles

• By using the host cell's machinery to produce energy for the virus

• By physically breaking open the host cell and releasing the viral particles

• By releasing a chemical that forces the host cell to produce new viral particles
