Examples
  • When the bacterium divides, the prophage is copied along with its DNA.
  • Scientists study prophages to understand their role in bacterial evolution.
  • Under certain conditions, the prophage can become active and cause the host cell to lyse.
Meaning
In a dormant state, the prophage can replicate along with the bacterial DNA and can be induced to enter a lytic cycle, leading to the production of new virus particles.
