FIG. 3.

Dimerization of HIV 1-331 transcripts in the presence of Gag or NC. ³²P-labeled HIV-1 1-331 RNA, prepared as described in Materials and Methods, was incubated with 0, 0.01, 0.02, 0.05, 0.10, 0.50, 1.0, 1.25, or 1.5 μg of NC (lanes 1 to 9) or 0, 0.08, 0.16, 0.4, 0.8, 4.0, 8.0, 10.0, or 12.0 μg of Gag (lanes 10 to 18). The results were analyzed by electrophoresis and autoradiography as described in Materials and Methods.
