A bacteriophage injects its DNA into an E. coli cell, which gets integrated into the bacterial chromosome, forming a prophage. What kind of life cycle the bacteriophage is undergoing?

Question

The keyword here is INTEGRATED, which means COMBINED, or JOINED. 

Whenever the genetic material of a virus is INTEGRATED into the genes of the host, 
then the virus is going through a LYSOGENIC life cycle. 

HIV (the virus that causes AIDS) is an example of a LYSOGENIC virus. 

When HIV gets into our cells, 
it mixes its genetic material with our DNA.
