 AB    Reverse transcription, the conversion of the single-stranded RNA genome
       into double-stranded DNA molecule, is a major event in the life cycle of
       retroviruses. We have shown that full-length unintegrated viral DNA in
       the cytoplasm of HIV infected cells is found in association with the
       viral proteins reverse transcriptase, integrase, matrix protein p17,
       protease and cellular histones, in a 320S replication complex. Using a
       one-step cell-to-cell transmission infection model, the stages of
       reverse transcription in HIV infection were investigated. The minus
       strong-stop and the first template transfer were detected as early as
       1.5 hours after infection, with completion of the full-length
       double-stranded DNA molecule by 3.5 hours, as detected by PCR. Evidence
       suggests that reverse transcription can proceed from initiation to
       completion within the 320s nucleoprotein complex.
