4. Research Questions Viral Replication
Lytic Cycle
What must happen in order for a virus to attach to the host cell?
Why would a bacteriophage like the one shown not be able to enter any other type of cell?
What must happen before new virus particles can be assembled?
What does the virus use from the host cell in order to make new viral nucleic acid and protein coats?
Lysogenic Cycle
What is the lysogenic cycle?
What is a provirus?
What happens to the provirus when the host cell reproduces?
How does the lysogenic cycle change to the lytic cycle?
What are examples of viruses that go through the Lysogenic Cycle?
