What does a bacteriophage accomplish with lysogeny? 1) it allows the bacteriophage to destroy the host cell's DNA. 2) it enables the bacteriophage to take over the cell. 3) it speeds up the viral infection cycle. 4) it allows the bacteriophage to infect cells it would not normally infect. 5) the genetic material of the bacteriophage can be passed on to future generations of infected cells.

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.
