Provirus

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.

Re:

... 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) ...

lysogeny

... the host, the genetic material will act in 2 ways (in RNA +sense virus) which are acting like another genetic material for the newly replicated provirus or act like mRNA to translate proteins for the capsid. You see that when this genetic material synthetizing the protein that they want, the ...
