Fig 6.

Presumed processes to generate provirus DNA from a genomic RNA of the 3′ LTR TTT or AAA mutant of HIV-1. A schematic represents provirus DNA production by overcoming mismatched 3′ termini between template RNA and minus-strand strong-stop cDNA (−sscDNA) is shown. The cases of the G1-form HIV-1 RNA of the 3′ LTR TTT mutant (upper panel) and an HIV-1 RNA beginning with two adenosines (an A2-form HIV-1 RNA of the AAA mutant, lower panel) are shown. RNAs and DNAs are written in blue and black, respectively.
