A virus that infects bacteria.
The word phage comes from the Greek and means to eat or ingest. There are different types of phages, each quite specific to a particular bacteria. Phage technology is a relatively new science which uses virus to infect and consume bacteria, although the beginnings date to the early 20th century.(It was discarded when antibiotics were discovered).

What phage in the reproductive cycle kills the bacterial host cell?
lytic
What are temperate phages?
A phage that can enter into lysogeny with its host. A phage that can become a prophage.
When a phage attaches to a bacterium what does the phage inject and what stays attached to the cell?
The part that remains outside is called the capsid or protein coat.
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 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/.
When the bacteriophage DNA becomes part of the bacterial chromosome?
During phage infection into bacteria, it penetrates phage DNA into bacterium,which will be integrated in to the bacterial genome (chromosome) to replicate and synthesize phage molecules.
When a T2 bacteriophage infects an E. coli cell what part of the phage enters the bacterial cytoplasm?
the whole phage
What phage in the reproductive cycle kills the bacterial host cell?
lytic
Phage typing is based on the fact that?
Bacterial viruses attack specific cells
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".
The development of virulent toxin producing bacterial strains due to the presence of a temperate phage can occur in?
specialized transduction
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 happens when a bacteriophage infects a bacteria cell?
When a bacteriophage infects a bacteria it enters either the lyctic or lysogenic cycle. the lyctic is the stages of: injection, reproduction, host destruction. The lysogenic cycle is when the virus' RNA mixes with the host cell's.
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 does a phage inject when it attaches to a bacterium?
Dna and phage body
