Abstract excerpt
The relatively low fidelity of DNA synthesis characteristic to the reverse transcriptases (RTs) of the AIDS-causing viruses, human immunodeficiency viruses types 1 and 2 (HIV-1 and HIV-2, respectively) was implicated as a dominant factor that contributes to the genetic hypervariability of these viruses. The formation of 3'-mispaired DNA and the subsequent extension of this DNA were shown to be key determinants...
