Unique Identifier : AIDSLINE ASHM5/94349028 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.
