Lytic vs Lysogenic Cycles

What type of organism do bacteriophages infect?

• Animal cells

• Plant cells

• Bacteria

• Fungi

What is the first step a bacteriophage takes when infecting a bacterium in the lytic cycle?

• It integrates its DNA into the bacterial chromosome.

• It injects its genetic material into the bacterium.

• It causes the bacterium to divide rapidly.

• It produces viral proteins immediately.

In the lytic cycle, what happens to the host bacterium's DNA after the phage injects its genetic material?

• It combines with the phage DNA to form a new chromosome.

• It is destroyed by the phage's genetic material.

• It remains intact and functions normally.

• It is replicated by the phage.

What is a key difference in the initial stage of the lysogenic cycle compared to the lytic cycle?

• The virus does not inject its DNA into the host cell.

• The host DNA is immediately destroyed.

• The viral DNA integrates itself into the host's chromosome.

• The host cell immediately produces new viruses.

How is the prophage DNA passed on to new bacterial cells in the lysogenic cycle?

• It is actively replicated by the virus.

• It is carried from generation to generation as the host cell divides.

• It is expelled from the host cell and infects new cells.

• It causes the host cell to lyse immediately.
