pubmed:abstractText |
A portion of poliovirus double-stranded RNA (25 to 50%) isolated from infected HeLa cells contains hairpin loops at one end of the duplex structure. These structures rapidly reformed double-stranded molecules after denaturation and appeared as molecules of up to two times genome length upon electrophoresis in denaturing agarose gels. A second form of poliovirus double-stranded RNA was readily denaturable into genome length strands. When the hairpin RNA was treated with S1 nuclease, subsequent denaturation resulted in formation of strands of up to genome length. Hairpin molecules contained very little, if any, poly(A) sequences, suggesting that the hairpin forms after nucleolytic removal of the 3' end of plus-strand templates. We conclude that the hairpin double-stranded RNA found in infected cells is likely generated by intracellular nicking and self-priming and that it does not represent an intermediate in the process of RNA replication.
