• Bacteria

Multiple Choice

Lytic infection and Lysogenic infection are two process used by viruses to______

• replicate inside a living cell

• replicate in the air

• replicate in liquids

​1) Lytic infection.

​•Replication of viruses using a host cell to make more viruses

•The viruses then burst out of the cell.

​2) Lysogenic infection.

​•The viral nucleic acid is inserted into the host cell’s DNA.

•There it is replicated along with the host DNA without damaging the host.

•Viral DNA is then called prophage

• The prophage can exit the bacterial chromosome and enter a lytic cycle.

Multiple Choice

The viral nucleic acid is inserted into the host cell’s DNA is called _____

• Prophage

• Viral RNA

• Prophase
