Bacteriophage T7 DNA Replication: A Linear Replicating Intermediate*

John Wolfson 1, David Dressler 1, Marilyn Magazin 1
PMCID: PMC426489  PMID: 4551146

Abstract

The T7 chromosome in the first round of replication is a Y-shaped DNA rod. Thus, it differs from previously observed bacterial and viral replicating chromosomes that are circular.

Keywords: gradient centrifugation, electron microscopy, E. coli, DNA partial denaturation
