Working in the laboratory, you infect host cells with a virus that is known to have both lytic and lysogenic life phases.Which result would definitively confirm that the virus has indeed entered a lysogenic phase?

Question

Quizplus · Accepted Answer

The detection of the viral genome integrated into the host cell genome is the definitive confirmation that the virus has entered a lysogenic phase. This is because during lysogeny, the viral genome is integrated into the host cell genome, and the viral genes are replicated along with the host cell genes. This allows the virus to persist in the host cell without causing lytic infection. In contrast, the other choices do not definitively confirm lysogeny, as they could also occur during a lytic phase or may not be related to viral infection at all.
