What can cause a phage in the lysogenic stage to revert to the lytic stage?

ultraviolet light


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.


Is Temperate phage lytic or lysogenic?

Temperate phages can exhibit both lytic and lysogenic cycles. In the lytic cycle, they infect a host bacterium, replicate, and cause the host to lyse, releasing new phage particles. In the lysogenic cycle, they integrate their genetic material into the host's genome, allowing the phage to replicate along with the host cell without causing immediate damage. This ability to switch between cycles is a defining characteristic of temperate phages.


How does the reproduction of HIV and lambda phage differ?

The Lambda Phage bacterial virus replicates itself whilst the HIV virus binds itself to existing cells and damages them. Lamba Phage increases with a "lysogenic" cycle, whilst the increase of HIV is known as "Lytic".

lysogenic

B) Lysogenic


What are temperate phages?

Temperate phages are bacteriophages that can follow two replication pathways: lytic and lysogenic. In the lytic cycle, they infect a bacterial host and replicate rapidly, causing cell lysis. In the lysogenic cycle, they integrate their DNA into the host genome, replicating along with the host without causing immediate cell lysis.


What happens first when a phage infects a bacterial cell and is going to enter a lysogenic cycle?

it becomes a part of the bacterial DNA and it can be replicated into the daughter cells. this cycle doesn't harm the bacterial cell but it can change into the lysis cycle and kill the host cell


What is the difference between a virulent phage and a temperate phage?

In virology, temperate refers to the life cycle some phages are able to perform. Atemperate phage can integrate its genome into its host bacterium's chromosome, becoming a lysogen known as a prophage. A temperate phage is also able to undergo lytic life cycles, where the prophage is expressed, replicates the phage genome and produces phage progeny and the progeny phage leave the bacterium. The virulent phages have only lytic lifecycles and thus infection results in the host cell's death (due to lytic cell destruction-the phage replicates itself and then bursts the cell, releasing many copies).


What is temperate phage superinfection immunity?

c. Repression of the phage genome - A phage coded protein, called a repressor, is made which binds to a particular site on the phage DNA, called the operator, and shuts off transcription of most phage genes EXCEPT the repressor gene. The result is a stable repressed phage genome which is integrated into the host chromosome. Each temperate phage will only repress its own DNA and not that from other phage, so that repression is very specific (immunity to superinfection with the same phage).Reference: http://pathmicro.med.sc.edu/mayer/phage.htm


What bacterium is pathogenic only when its lysogenic?

The bacterium that is pathogenic only when lysogenic is Streptococcus pyogenes. It can become virulent by acquiring a lysogenic bacteriophage that carries genes for toxins, such as the pyrogenic exotoxins, which can lead to diseases like scarlet fever and streptococcal toxic shock syndrome. In its non-lysogenic state, S. pyogenes can still cause infections but lacks the enhanced virulence associated with the phage. Thus, lysogeny plays a crucial role in its pathogenic potential.


What is Campbell model of lambda phage?

The Campbell model of lambda phage describes the genetic recombination that occurs during the lysogenic cycle of the bacteriophage lambda. In this model, the phage DNA integrates into the host bacterium's chromosome through homologous recombination, allowing the viral DNA to be replicated along with the host's DNA during cell division. This integration process is critical for the establishment of the lysogenic state, where the viral genome remains dormant until triggered to enter the lytic cycle. The model emphasizes the role of specific sequences and enzymes in facilitating this integration.
