A viral pathway in which viral DNA is incorporated into the host cell’s DNA and copied as that cell divides, without immediately producing new virus particles.

Specification 5.7B · Paper 1
Revise: Lifecycle of a VirusIn the lysogenic pathway, viral DNA becomes incorporated into the host cell’s DNA. It does not immediately make a large number of new virus particles or burst the cell. Instead, when the host cell divides, it copies the viral DNA along with its own DNA, so the new cells carry it too.
For the lysogenic pathway, state that viral DNA becomes part of the host cell’s DNA and is copied when the host cell divides; explain that the lytic pathway can begin later.
