What is a virus that reproduces in a bacterium called?
A bacteriaphage (literally bacteria eater) is a virus that reproduces in a bacterium.
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.
A virus that reprduces in a bacterium is called a?
bacteriophage (literally, phage = eat, bacterio = bacteria)
What is the difference between virulent phage and prophage?
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.
A bacteriophage typically attaches to the bacterium and then?
It's genetic material and some enzymes sometimes which hijack the bacteria into making more viruses.
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.
A virus that reproduces in a bacterium is called?
phage
When phage attaches to a bacteria the phage injects what?
DNA single

The bacteriophage attaches to the bacterium's?
surface

How does the size of a virus compare with the size of a bacterium?
A virus is much much much smaller then a bacterium. Virus called phage can infect bacteria.
During which process does one bacterium inject its DNA into another bacterium through thin tube called a pilus?
Transduction
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/.
