title: Permutation of the DNA in small-headed virions of coliphage P1.
abstract: Use of restriction endonucleases Bg/II, EcoRI, BamHI, and HindIII, has established that in small-headed (P1S) virions of coliphage P1, as a population, the entire genome found in big-headed (P1B) virions is represented. In addition, the origin and direction of DNA packaging are identical in P1S and P1B virions.
