How are the normal functions of the host cell affected by the provirus?
The provirus integrates into the host cell's DNA and can disrupt normal gene expression and signaling pathways. This interference may alter the cell's functions, leading to changes in growth, differentiation, or metabolism. In some cases, this can lead to uncontrolled cell division and potentially contribute to the development of diseases like cancer.
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.
What is the significance of the formation of a provirus?
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 is the viral DNA that is embedded in a host's DNA?
The viral DNA that is embedded in a host's DNA is called a provirus.
What type of infections pathway is associated with a prophage or provirus?
Lysogenic pathway is associated with a prophage or provirus infection. In this pathway, the genetic material of the virus gets integrated into the host cell's DNA and remains dormant until it is triggered to enter the lytic pathway.
During the lysogenic cycle is a provirus part of a host cell's chromosome?
Yes, during the lysogenic cycle of a viral infection, a provirus integrates into the host cell's chromosome. The provirus DNA becomes part of the host cell's genetic material and is replicated along with the host DNA during cell division.
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.

Because the provirus makes the host reproduce

Is a provirus a temperate virus?
Yes, a provirus is a type of temperate virus. A provirus is a form of a virus that has integrated its genetic material into the host cell's DNA, remaining dormant until it is activated. Temperate viruses can exist in both the lytic and lysogenic cycles, with the lysogenic cycle involving integration of viral DNA into the host genome to form a provirus.

How are provirus and retrovirus the same?
A retrovirus is a virus that injects RNA into the cell, the RNA then goes through reverse-transcription. It gets turned into DNA and splices with the host cells DNA. Then the cell will make more RNA and produce protien. A provirus just injects DNA and either goes through the lytic cycle or the lysogenic cycle.
How is pathogen and provirus related?
A provirus is a form of a pathogen that has integrated into the host's DNA and can remain latent until it is activated to produce a new infectious virus. Pathogens can become proviruses by integrating their genetic material into the host cell's genome.
What is it called when the integrated DNA does not produce new HIV but remains hidden in the host cell's chromosomes?
Lysogenic cycle. Hidden in the DNA the virus is termed a provirus.
What is the viral DNA that is embedded in a host's DNA?
The viral DNA that is embedded in a host's DNA is called a provirus.
What must reproduce inside a virus?
Nothing reproduces inside a virus. It has to latch on the a host cell and insert its' DNA or RNA and then make the host cell reproduce virus particles.
