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 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.
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.
During the lysogenic cycle is a provirus part of a host cell's chromosome?
Yes
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 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.
Lysogenic and lytic viral stages?
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
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.
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.
What is provirus?
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.

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.
