When a virus is latent and inserts its DNA into the host cells genome, we call this what phase?
|
|
Lysogenic
|
|
|
Lytic
|
|
|
Both lysogenic and lytic
|
|
|
None of the above
|
Explanation:
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. Environmental stressors such as starvation or exposure to toxic chemicals may cause the prophage to be excised and enter the lytic cycle.
