A, schematic representation of HIV-1 subgenomic plasmids pNL13a7 (7), pNL13a7de3, and pNL13a7di3. Nucleotide positions of deletions are indicated. B and C, Northern blots with RNA extracted from HeLa cells transfected with pNL13a7 (w), pNL13a7de3 (de3), or pNL13a7di3 (di3) in the absence or presence of CMV promoter-driven plasmids expressing SRp55 or SRp75. The blots were probed with exon 1 probe (Fig. 1A) detecting all HIV-1 mRNAs. Detected mRNAs are indicated.
