Definitions

from The American Heritage® Dictionary of the English Language, 5th Edition.

  • noun A form of a virus that allows it to be integrated into the genome of a host cell and to replicate in concert with the cell's genetic material without causing cell lysis.

  • noun A virus genome, such as HIV, that integrates itself into the DNA of a host cell so as to be passively replicated along with the host genome.

  • noun cDNA copy of the RNA genome of a retrovirus; the genetic material of a virus as incorporated into and able to replicate with the genome of a host cell

Examples

  • This DNA copy, called a provirus, makes RNA copies, and the virus is regenerated, phoenixlike, to form new viruses.

    The Emperor of All Maladies

  • This DNA copy, called a provirus, makes RNA copies, and the virus is regenerated, phoenixlike, to form new viruses.

    The Emperor of All Maladies

  • This DNA copy, called a provirus, makes RNA copies, and the virus is regenerated, phoenixlike, to form new viruses.

    The Emperor of All Maladies

  • This DNA, known as the provirus, then integrates itself into the host cell's chromosomes.

    Aids The Next Ten Years

  • Opportunity No. 3 arises shortly after the provirus (the integrated viral DNA) starts running off RNA copies of itself.

    Aids The Next Ten Years

  • The trouble begins when the provirus starts directing enzymes in the host cell to produce new strands of viral RNA.

    Aids The Next Ten Years

  • Often this results in permanent provirus status and incorporation to the genome.

    Of Prions and People - The Panda's Thumb

  • The point that we are making is that we are in the beginning of an epidemic stemming from a provirus in our genomes.

    Invasion

  • SV40 (6), the viral DNA becomes a provirus, i.e. it establishes permanent, covalent bonds with the cellular DNA.

    Renato Dulbecco - Nobel Lecture

  • The provirus thus became a tool for studying regulation of DNA transcription in animal cells.
