Proviruses are RNA fragments from viruses that become integrated into the DNA of the host. It will replicate as the host DNA does and cause no harm.
However, they can become active and take over the cell as do other viruses.
About 8% of human DNA is from proviruses and are called inherited endogenous (belong there) retrovirus.

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 viral DNA incorporated in bacterial DNA called?
The introduction of viral DNA into the host genetic structure is called lysogeny. And this is lysogenic cycle.
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.

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.

provirus
During the lysogenic cycle is a provirus part of a host cell's chromosome?
Yes
