Reverse transcriptase, the enzyme responsible for copying viral RNA into cDNA prior to integration into the host genome, lacks 3'-to-5' exonuclease "proofreading" ability. This may seem like a disadvantage to organisms that depend on such enzymes, but in fact they turn it to their advantage. How is this so?
