temperate refers to the life cycle some phages are able to perform. A temperate 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).
So they are both the same in that they both require a host cell to reproduce. They both can have lytic lifecycles but only the temperate phage can "hitch a ride" in the host cell by integrating into the genome.

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.
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 does a phage inject when it attaches to a bacterium?
Dna and phage body
What is the function of bacteriophage?
The function of bacteria is to reproduce. Bacteria is a large domain of prokaryotic microorganisms. They are also the cause of human and animal diseases. Some bacteria, like those in the intestines are friendly and needed for digestion.
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 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 are temperate phages?
A phage that can enter into lysogeny with its host. A phage that can become a prophage.
What type of phage enters an inactive prophage stage?
viruses

What is a harmless bacteriophage?
First I'll answer what a bacteriophage is. A bacteriophage is a type of virus that infects a bacterium. These phages can be either virulent or temperate. Virulent phages are capable of infecting and even killing the bacterium it has infected. Temperate phages usually do not cause harm. Its DNA is incorporated into the bacterium's DNA creating what is called a prophage. I don't really know what you are looking for when it comes to "harmless". A harmless phage is one that either only infects a specific bacteria and not the cells of say a human. This is called phage therapy. It is used for bacterial infections in human. The phages kill the bacteria but doesn't infect the human cells. It used to be big in the former Soviet Union but has kind of fell off. I do believe that it is starting to pick up momentum again however. The second thing i guess a harmless phage would mean is the temperate phage that does not harm the bacteria it has infected. If this is what you are looking for, google temperate phage or prophage. You should be able to find the info you need/.
The development of virulent toxin producing bacterial strains due to the presence of a temperate phage can occur in?
specialized transduction
What is the difference between a bacteriaiophage and a prophage?
A bacteriophage is a completely assembled virus capable of landing on a bacterium and injecting it's genetic material in lysis, or a lysogenic attack. A provirus is a virus that has incorporated it's genetic material into the genetic material of the host for continual replication, thus, " before " the phage. This is the lysogenic phase of viral attack.
