What else can I help you with?
Does prophage replicate along with its host?
Yes, a prophage replicates along with its host's DNA during the lysogenic cycle of a bacteriophage. When a bacteriophage infects a bacterial cell, it can integrate its genetic material into the host's genome, forming a prophage. As the host cell divides and replicates its DNA, the prophage is also copied and passed on to the daughter cells. This allows the viral genetic material to persist in the bacterial population without causing immediate lysis.
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.
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.
The lysogenic cycle is a viral reproductive cycle in which?
The viral DNA molecule is incorporated by genetic recombination into a specific site on the host cell's chromosome (chromatin body). it is then called prophage, the viral DNA incorporate into bacterium DNA , one prophage gene codes for a protein that represents most of the other prophage genes. the phage DNA along with its own and passes on the copies to the daughter cells. A single infected cell can soon give rise to a large population of bacteria carrying the virus in prophage form. So this propagate mechanism enables virus without killing the host cell's.
An infection in which DNA of a virus is embedded into a host cell and replicates with host DNA is called what?
This process is called lysogeny, and the host cell is referred to as a lysogenic cell. The integrated viral DNA is known as a prophage.
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 of a bacteriophage (virus that targets bacteria) that is inserted and integrated into the circular bacterial DNA chromosome or plasmid. Bacteriophages reproduce by inserting their genome into that of a bacterium and thus getting their genes read and viral proteins produced.
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 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.
What is a prophage-?
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 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.
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.
