A prophage is a phage genome that is integrated into the DNA of a bacterial host and replicates along with the host's DNA. It remains dormant within the host cell until it is triggered to enter the lytic cycle, where it replicates and eventually lyses the host cell.

What is viral DNA incorporated in bacterial DNA called?
Viral DNA incorporated in bacterial DNA is called a prophage.
What is the phage DNA that is integrated into a host cell's chromosome is called a?
Phage DNA that is integrated into a host's cell chromosome is a bacteriophage. They behave as lytic or lysogenic. Lytic breaks open the host after replication, , lysogenic does not destroy the host.
What is a prophage gene?
A prophage gene is a gene that is integrated into the DNA of a bacteriophage. When a bacteriophage infects a bacterial cell, its DNA can integrate into the host cell's genome as a prophage. Prophage genes are then potentially passed on to daughter cells when the bacterium divides.
What is the fate of the prophage during the lysogenic stage?
During the lysogenic stage, the prophage inserts its DNA into the host bacterium's chromosome and replicates along with the host DNA. It is passed down to daughter cells during replication, ensuring its persistence within the host genome. The prophage remains dormant until triggered to enter the lytic cycle by external factors.
What kinds of factors can cause a prophage to become virulent?
Factors such as UV light exposure, certain chemicals or drugs, stress to the host cell, or changes in environmental conditions can trigger a prophage to become virulent by inducing the lytic cycle and leading to the production of viral particles. These triggers can disrupt the lysogenic cycle and activate the lytic genes within the prophage.

Can a prophage pop out of a chromosome?
yes it can pop out of the chromosomes
What type of phage enters an inactive prophage stage?
A temperate phage is a type of phage that can enter an inactive prophage stage by integrating its DNA into the host cell's genome. In this stage, the prophage replicates along with the host cell's DNA and can be passed on to daughter cells during cell division.
What type of viral infection includes the formation of a prophage?
Parhogen
What is a prophage made of?
A prophage is made up of proteins that replicate a virus within a cellular structure. The virus does not disrupt the cellular structure of the bacteria, and waits for the lytic cycle to begin so it can replicate.
What does pi209 mean?
prophage pi2 protein 09; - == protein-coding
Why are lysogens immune to superinfections?
Lysogens are immune to superinfections because they already contain a prophage (viral DNA) integrated into their bacterial genome. This prophage confers immunity by blocking the entry of new phages or preventing their replication inside the host cell. This phenomenon is known as superinfection immunity.
What is the fate of the prophage during the lysogenic stage?
During the lysogenic stage, the prophage inserts its DNA into the host bacterium's chromosome and replicates along with the host DNA. It is passed down to daughter cells during replication, ensuring its persistence within the host genome. The prophage remains dormant until triggered to enter the lytic cycle by external factors.

These triggers can disrupt the lysogenic cycle and activate the lytic genes within the prophage.
What type of infections pathway is associated with a prophage or provirus?
Lysogenic pathway is associated with a prophage or provirus infection. In this pathway, the genetic material of the virus gets integrated into the host cell's DNA and remains dormant until it is triggered to enter the lytic pathway.
