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

1

replicate inside a living cell

2

replicate in the air

3

replicate in liquids

23

1) Lytic infection.

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.
