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.
When the cell reproduces, the provirus is copied as part of the chromosome. The virus chromosome is placed into the host cell's.
A virion is an entire virus particle. It is the complete form of a virus with an outer protein shell, an inner core of DNA or RNA, and a capsid.
lysogenic infection
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.

The term pathogen most commonly is used to refer to infectious organisms. The inactive form of a virus is called a provirus. -ChaCha Answers

The host cell would have transgenic DNA. A vector is often used to this.

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.
