Question

Under certain ________, the viral DNA loses its integrated status and initiates replication, phage reproduction and lysis of the bacterium.

Answer 1

Under stressful conditions, phage DNA is excised from the bacterial chromosome and enters the lytic cycle, resulting in the replication of the phage and lysis of the host cell.

Step-by-step explanation:

Under stressful conditions, the phage DNA is excised from the bacterial chromosome and enters the lytic cycle. In the lytic cycle, the phage replicates and lyses the host cell, resulting in the release of phage particles. This is different from the lysogenic cycle, where the phage DNA is incorporated into the bacterial genome and is passed on to subsequent generations.
