lysogenic cycle

Detailed explanation-1: -In lysogenic infection, viral DNA gets integrated with the host cell’s DNA, where it is copied along with the host cell’s DNA when the host cell replicates. Viral DNA multiplies as the host cell multiplies. Each new daughter cell created is infected with the virus’ DNA.
Detailed explanation-2: -In the lysogenic cycle, phage DNA is incorporated into the host genome, forming a prophage, which is passed on to subsequent generations of cells.
Detailed explanation-3: -Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction (the lytic cycle being the other). Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium’s genome or formation of a circular replicon in the bacterial cytoplasm.
