Because the provirus makes the host reproduce
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.
When the cell reproduces, the provirus is copied as part of the chromosome. The virus chromosome is placed into the host cell's.
The host cell would have transgenic DNA. A vector is often used to this.
Yes
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.
Lysogenic cycle. Hidden in the DNA the virus is termed a provirus.
Well im just going to type what it says in my bookIn bacterial viruses, the cycle of the viral infection, replication, and destruction is called the lytic cycle.During an infection, some viruses stay inside the cells but do not make new viruses. Instead of producing virus particles, the viral gene is inserted into the host chromosome and is called a provirus. Whenever the cell divides, the provirus also divides, resulting in two infected host cells. In this cycle, called the lysogenic cycle, the viral genome replicates without destorying the host cell. In some lysogenic viruses, change in the environment can causethe provirus to begin the lytic cycle, which means the destruction of the host cell.I hope this helps ^.^ --Pengi-Chan
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.
The introduction of viral DNA into the host genetic structure is called lysogeny. And this is lysogenic cycle.
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.
