RESUMO

The cleavage map of H-1 replicative-form DNA to the bacterial restriction endonuclease EcoRI, HaeII, HaeIII, HindII, HindIII, and HpaII has been determined. The 5'-phosphoryl end of the viral strand is on the right end of the molecule at or near the replication origin. Evidence is presented for the presence of inverted self-complementary sequences at the right end that differ from those at the left end. These sequences allow a foldback of the DNA after denaturation, and a minority of the native replicative-form DNA has the foldback configuration. The possible role of these structures in H-1 DNA synthesis is discussed.
