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.

A provirus is a viral genome that is integrated into the host genome and can replicate alongside the host cell. A virion is a complete virus particle consisting of genetic material (DNA or RNA) surrounded by a protein coat, and is capable of infecting host cells. In simple terms, a provirus is when the virus is integrated into the host cell's DNA, while a virion is the infectious form of the virus.

What happens to the provirus when the host cell reproduces?
When the host cell reproduces, the provirus is replicated along with the host cell's DNA. As the host cell divides, each daughter cell also inherits a copy of the provirus, which integrates into the genome of the new cells.
What is the size of virion?
The size of a virion can vary depending on the virus, but they are typically between 20 to 300 nanometers in diameter. Virions are generally smaller than bacteria and can only be viewed using an electron microscope.
What the differences between virion and virus?
A virion is a complete, infectious virus particle with a nucleic acid core surrounded by a protein coat or envelope. A virus, on the other hand, is a complex entity that includes not only the virion but also the infected host cell and the process of viral replication. In short, a virion is a single infectious particle, while a virus refers to the entire infectious entity.
What is virion?
A virion is a complete virus particle outside a host cell, consisting of genetic material (either DNA or RNA) surrounded by a protein coat known as a capsid. Virions are the infectious form of a virus that can transmit its genetic material to infect a host cell and replicate.
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.
When did Pierre Virion die?
Pierre Virion died in 1988.
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 is the morphology of a virion?
N/a
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.
What happens to the provirus when the host cell reproduces?
When the host cell reproduces, the provirus is replicated along with the host cell's DNA. As the host cell divides, each daughter cell also inherits a copy of the provirus, which integrates into the genome of the new cells.
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 the term for a virus particle that does not have a host?
A virus particle that does not have a host is called a "virion." Virions are the infectious form of a virus that is capable of spreading to other hosts.
What is a single cell virus particle called?
A single cell virus particle is called a virion. It consists of genetic material enclosed in a protein coat.
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.
How big is the Alfalfa mosaic virus?
It is rather small. The range for the length of the virion particle is about 30-57 nm. Since it is a virion , it is smaller than any virus.
What structural property of a virion has in common with cellular organism?
A virion is the infectious form of a virus outside of the cell before it invades. Both cells and viruses have genetic material.
