Dictionary » P » Provirus



(Science: virology) The genome of a virus when it is integrated into the host cell dNA. In the case of the retroviruses, their rNA genome has first to be transcribed to DNA by reverse transcriptase. The genes of the provirus may be transcribed and expressed or the provirus may be maintained in a latent condition. The integration of the oncogenic viruses, such as papovaviridae and retroviruses can lead to cell transformation.

Disease that target genes? Host affected or offspring only?

Viruses insert proviruses into cells. The provirus is the genetic code for that virus. This is how a virus can turn a cell into a virus factory. However, some proviruses can remain latent, so an infected cell will pass on that provirus ...

Questions regarding bloodborne viruses...

look up the term "provirus". This is when a virus' DNA inserts itself into the host's genome. You could make it so the bad guy has only a certain place in his genome where it would attach, but look up basic virus stuff to get ...

Invasion of a host cell by a DNA virus

... cell once invaded. During the lysogenic cycle the viral nucleid acid joins to a specific site of the host cells chromosome, this is known as the provirus. This provirus lays dormant and as the host cell reproduces it replicates its own DNA as well as the provirus meaning that both daughter molecules ...

... order for it replicate using the host machinery, it must produce a DNA copy of its genome to insert into the genome of the host, which is termed a provirus. It does so by the reverse transcriptase it encodes, which is a DNA dependant RNA polymerase. All living things (therefore not including viruses) ...
