title: Viral DNA-synthesizing intermediate complex isolated during assembly of bacteriophage phi X174.
abstract: A DNA protein complex that is a precursor of mature phi X174 phage was isolated. The complex sedimented with an S value of 50 in a sucrose gradient and contained phage DNA consisting of a replicative form molecule with an extended tail of single-stranded viral DNA. The viral-strand DNA ranged from one to two genomes in length. Proteins coded on the phi X174 genome as well as the host genome were associated with the viral DNA in the 50S precursor complex. Our results indicated that both viral DNA synthesis and cleavage of the growing viral-strand DNA occurred in the 50S complex.
