Retroviruses, including HIV and HTLV I, a cause of one type of human leukemia. They synthesize DNA "backwards". They accomplish this by means of reverse transcriptase that comes each virus particle.
This way, when the DNA of some retroviruses becomes inserted into the host's DNA as a provirus, cells may be transformed and produce tumors. Insertion allows HIV to remain latent in an infected cell for several years. They are not called proviruses unless they remain with the host DNA through many divisions and even given from parent to offspring.

How is pathogen and provirus related?
The term pathogen most commonly is used to refer to infectious organisms. The inactive form of a virus is called a provirus. -ChaCha Answers
A host chromosome with a viral gene inserted into it is a?
The host cell would have transgenic DNA. A vector is often used to this.
What is it called when a virus hides for a while as part of bacterial chromosome?
provirus
During the lysogenic cycle is a provirus part of a host cell's chromosome?
Yes
Does smallpox form a provirus?
No. The are different from other pox viruses in that they replicate in the cytoplasm and not the nucleus.
How are the normal functions of the host affected by the provirus?
Because the provirus makes the host reproduce
What does a provirus cause?
a latent infection
What happens to the provirus when the host cell reproduces?
When the cell reproduces, the provirus is copied as part of the chromosome. The virus chromosome is placed into the host cell's.

What type of infections pathway is associated with a prophage or provirus?
lysogenic infection

What is the difference of PROVIRUS and VIRION?
A provirus is the virus' genetic material integrated with the genetic material of the host cell. Some viruses stay in this form inside a cell until a specific stimulus causes the provirus to start to reproduce and lyse, or burst, the cell. For instance, some prophages (a provirus from a bacteriophage) the process doesn't continue until UV radiation hits the bacterium. A virion is the name of the actual virus particle. The virion is comprised of the capsid and the DNA (or RNA) of the virus. The term virion is used in a similar way that bacterium is when referring to a single bacterial cell. Some virions, such as HIV also have a phospholipid bilayer that they gain by 'budding' from the host cell. When a cell is lysed the provirus gives way to viral progeny, the virions.
How are the normal functions of the host cell affected by the provirus?
A virus can: 1. Kill the host cell 2. Alter the cell; incorporate into the genetic material of the host cell, thus becoming part of its nucleic acid pool; or divide when the host cell divides.
What is the dormant state of a virus called?
The lysogenic cycle. This is when the virus incorporates its genetic material into the hosts genetic material and becomes what is called a provirus.
