A researcher infects a bacterium with a bacteriophage and notices that the infection does not immediately bring about the destruction of the host cell.Instead,the phage genetic material is copied whenever the host reproduces.Which viral replication cycle is described here?
A) integration cycle
B) lysogenic cycle
C) biosynthetic cycle
D) lytic cycle
E) emergence cycle

The fact that the phage genetic material is copied whenever the host reproduces indicates that the bacteriophage has integrated its genetic material into that of the host bacterium, rather than immediately causing cell lysis, which would be characteristic of the lytic cycle. This suggests that the bacterium and bacteriophage are undergoing the lysogenic cycle, which involves integration of the bacteriophage genetic material into the host genome followed by replication along with the host DNA during subsequent cell divisions. The biosynthetic cycle and emergence cycle are not recognized viral replication cycles, while the lytic cycle involves immediate cell lysis rather than a lysogenic phase.
