Bacteriophage T7 DNA replication: a linear replicating intermediate (gradient centrifugation-electron microscopy-E. coli-DNA partial denaturation).
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.
