FIG. 6.
Infection of MHIV-mMA12CA is blocked at nuclear transport. Reverse transcription and nuclear transport of MHIV-mMA12CA and parental HIV-1 were monitored by measuring late reverse transcription products (upper) and 2-LTR circles (lower) as markers, respectively. Increasing amounts of virus inocula (x axis) were challenged with either normal or nondividing cells. The y axis indicates the copy number of each DNA analyzed with real-time quantitative PCR.
