When the bacteriophage DNA becomes part of the bacterial chromosome?
When bacteriophage DNA becomes integrated into the bacterial chromosome, it is known as lysogeny. The integrated phage DNA is called a prophage. During lysogeny, the bacteriophage DNA remains dormant, replicating along with the bacterial chromosome. Under certain conditions, such as stress, the prophage can become activated and enter the lytic cycle, leading to viral replication and cell lysis.
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
Generalized transduction differs from specialized transduction in that generalized transduction?
GENERALIZED TRANSDUCTION- Is the type of transduction in which a fragment of DNA from the degraded chromosome of an infected bacteria cell is accidentally incorporated into a new phage particle during viral replication and thereby transfered to another bacterial cell. specialized- is the type in which the bacterial DNA transduced is limited to one or a few genes lying adjacent to a pro-phage that are accidentally included when the phage is excised from the bacterial chromosome.
What kind of cell does a phage infect?
A phage infects bacterial cells by injecting its genetic material into the host bacterium. Once inside, the phage hijacks the bacterium's cellular machinery to replicate and produce more phage particles, ultimately leading to the bacterium's destruction.
The substance a phage leaves outside its host cell?
The substance a phage leaves outside its host cell is typically referred to as the "phage progeny" or "phage particles." These particles can include newly synthesized phage DNA and proteins, as well as the phage capsid that encapsulates the genetic material. This material can go on to infect other host cells and continue the phage replication cycle.

The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cells chromosome is called the?
motor cycle

The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cell's chromosome is called the?
lysogenic
What are phage vectors?
"Vector" is an agent that can carry a DNA fragment into a host cell. If it is used for reproducing the DNA fragment, it is called a "cloning vector". If it is used for expressing certain gene in the DNA fragment, it is called an "expression vector".Commonly used vectors include plasmid, Lambda phage, cosmid and yeast artificial chromosome (YAC).
The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cell's chromosome is called the cycle?
B) Lysogenic
A virus that reproduces in a bacterium is called?
phage
The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cells chromosome is called the what cycle?
The viral reproductive cycle you are describing is called the lysogenic cycle. In this cycle, the viral DNA integrates into the host cell's chromosome, remaining dormant until it is triggered to enter the lytic cycle.

What A bacteriophage injects its DNA into an E. coli cell which gets integrated into the bacterial chromosome forming a prophage. What kind of life cycle the bacteriophage is undergoing?
The bacteriophage is undergoing a lysogenic life cycle. In this process, the phage DNA integrates into the bacterial chromosome, forming a prophage, which can remain dormant and replicate along with the host cell's DNA during cell division. This allows the viral genetic material to be passed on to daughter cells without causing immediate lysis of the bacteria. The lysogenic cycle can eventually switch to the lytic cycle under certain conditions, leading to the production of new phage particles and cell lysis.
The substance a phage leaves outside its host cell?
The substance a phage leaves outside its host cell is typically referred to as the "phage progeny" or "phage particles." These particles can include newly synthesized phage DNA and proteins, as well as the phage capsid that encapsulates the genetic material.
