The process of infection with bacteriophage phi-X174. XXI. Replication and fate of the replicative form.

Abstract
The nascent daughter replicative form (RF)n molecules synthesized during the period of RF replication are of 2 kinds, present in equal amounts. In one, the viral strand is open; in the other, the complementary. During the period of single-strand DNA formation, the viral strands of the daughter RF molecules were released and became part of the accumulation of progeny single-stranded DNA molecules (in virus particles).
