Single-stranded regions on unintegrated avian retrovirus DNA.
Using chromatography on benzoylated naphthoylated DEAE-cellulose, we found that greater than 99.5% of the unintegrated linear viral DNA species detected in quail embryo cells infected with Rous sarcoma virus contained single-stranded regions, even at 16 h after infection. These regions were distributed across the genome and, on average, were primarily of plus-strand DNA. Within most of the linear viral DNA species, the minus strand was interpreted as being of genome size with two copies of the large terminal redundancy, LTR. In contrast, the plus strands in the linear viral DNA species were exclusively subgenomic.
