title: Replicative hybrid of T4 bacteriophage DNA.
abstract: Hybrid density replicative T4 DNA was isolated from CsCl, sheared, and reanalyzed in CsCl. The results rule out a branched model for T4 DNA replication and confirm that T4 DNA replicates to a conventional, semiconservative, colinear hybrid.
