Understanding Lytic and Lysogenic Pathways in Viruses

What does the blue color represent in the virus structure?

• Viral enzymes

• Genetic material

• Protein coat

• Host cell DNA

What is the role of the protein coat in a virus?

• To replicate the viral DNA

• To protect the viral genetic material

• To integrate the viral DNA into the host's DNA

• To produce energy for the virus

How does a virus begin to infect a cell?

• By merging with the cell's membrane

• By consuming the cell's nutrients

• By attaching and injecting its genetic material into the cell

• By replicating its DNA inside the cell

How does the virus initially interact with the host cell?

• By directly entering the nucleus

• By hiding from the cell's immune response

• By disrupting the cell's membrane

• By binding to the cell's surface

How are new viruses formed in the lytic pathway?

• By division of the host cell

• By assembly of viral components inside the host cell

• By external addition of viral particles

• By the host cell's DNA replicating the virus

What is the result of cell lysis in the lytic pathway?

• The cell becomes immune to further infections

• The cell's DNA is integrated with the virus

• The virus becomes dormant

• New viruses are released to infect other cells

What happens to the host cell at the end of the lytic cycle?

• It splits open, releasing new viruses

• It is transformed into a viral factory

• It becomes immune to further viral infections

• It survives and continues to function

What is the significance of cell lysis in virus propagation?

• It repairs the damaged host cell

• It signals the end of the viral infection

• It helps in the integration of viral DNA into the host's DNA

• It releases newly formed viruses to infect other cells

In the lysogenic pathway, what happens to the viral genetic material?

• It remains dormant until the cell is under stress

• It integrates into the host's DNA

• It is immediately used to create new viruses

• It destroys the host's DNA

What is the fate of the host cell's DNA in the lysogenic pathway?

• It is expelled from the cell

• It replicates along with the viral DNA

• It remains unaffected by the viral DNA

• It is immediately destroyed
