A prophage:
1) is phage DNA that is integrated into viral DNA.
2) is phage DNA that is integrated into bacterial DNA.
3) replicates only when the eukaryotic cell it infects replicates.
4) is an underdeveloped lytic virus.
5) is a bacterial cell about to lyse.



Answer :

Final answer:

A prophage is phage DNA integrated into bacterial DNA, forming when a temperate bacteriophage infects a bacterium.


Explanation:

A prophage is phage DNA that is integrated into bacterial DNA. It forms when a temperate bacteriophage infects a bacterium and incorporates its DNA into the host cell's genome. The virus remains dormant in the host cell until induced, leading to excision of the prophage and entry into a lytic phase.
