Viral DNA is inserted into host DNA, and is replicated when the cell divides.
Virus is an infectious agent that cannot replicate on its own, but needs a host to do so. The virus has its own genes (DNA or RNA) surrounded by proteins. The virus then infects the cell and synthesizes its genes to form new viruses.
Viruses have three main parts: their genetic material, a protein coat that will protect this genetic material called a capsid, and a lipid bilayer that will surround the entire virus, which will be its envelope.
Therefore, we can confirm that viral DNA is inserted into host DNA, and is replicated when the cell divides.
