Which infection cycle is characterized by retention of the phage DNA molecule in the host bacterium for many thousands of cell division?

Which infection cycle is characterized by retention of the phage DNA molecule in the host bacterium for many thousands of cell division? Correct Answer Lysogenic cycle

With many lysogenic phages the phage DNA is inserted into the bacterial genome in a manner similar to episomal insertion. The integrated form of the phage DNA is called the prophage and bacterium is referred to as a lysogen.
