What is Retrovirus?
A '''retrovirus''' is any [[virus]] which copies itself as part of the cell's [[DNA]] by [[transcription (genetics)|reverse transcribing]] its [[RNA]]. Since the cell cannot proofread the step in which RNA is converted back to DNA, errors often go unnoticed. This changes the exact sequence of a retrovirus' RNA frequently. This makes it harder for retroviruses to be attacked by drugs. [[HIV]] is a retrovirus, which makes it very difficult to overcome using drugs. ==Related pages== *[[RNA virus]] *[[Virology]] == Other websites == * [http://www.retrovirology.com Retrovirology] Scientific journal * [http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/R/Retroviruses.html Retroviruses at rcn.com] {{Webarchive|url=https://web.archive.org/web/20130329004127/http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/R/Retroviruses.html |date=2013-03-29 }} [[Category:Viruses]] {{science-stub}}
