Understanding the Lytic Cycle

What is the first step of the lytic cycle in a bacteriophage virus?

• The virus injects its nucleic acid into the cell.

• The virus attaches itself to a bacterial cell.

• The virus uses the cell's ribosomes to make virus proteins.

• The virus breaks up the cell's DNA.

What is the primary role of the virus's nucleic acid once inside the host cell?

• To attach to the bacterial cell.

• To use the cell's ribosomes to make virus proteins.

• To form a protein capsid.

• To destroy the host cell's ribosomes.

What happens to the host cell's DNA during the lytic cycle?

• It is replicated by the virus.

• It is broken up by the virus proteins.

• It is used to create new viruses.

• It remains unchanged.

Which component of the virus is responsible for attaching to the bacterial cell?

• Nucleic acid

• Ribosomes

• Protein capsid

• Tail section

What is the structure of a lytic bacteriophage virus?

• A complex organism with multiple cells

• A simple structure composed of a protein capsid, nucleic acid, and a tail section

• A single-celled organism with a nucleus

• A complex structure with multiple organelles

What is the main purpose of the lytic cycle for a virus?

• To create energy for the host cell

• To reproduce and create more viruses

• To protect the host cell from other viruses

• To repair the host cell's DNA

Which of the following is NOT a component of a lytic bacteriophage virus?

• Protein capsid

• Nucleic acid

• Ribosomes

• Tail section

What happens to the virus capsid and tail after the nucleic acid is injected into the host cell?

• They are used to create new viruses.

• They remain outside the host cell.

• They are broken down by the host cell.

• They enter the host cell to assist in replication.

In the context of the lytic cycle, what is the role of the host cell's ribosomes?

• To attach the virus to the host cell

• To break up the virus's nucleic acid

• To make virus proteins

• To protect the host cell's DNA

What is the outcome for the host cell at the end of the lytic cycle?

• The host cell is repaired and continues to function normally.

• The host cell is destroyed, releasing new viruses.

• The host cell becomes immune to further infections.

• The host cell becomes a permanent host for the virus.
