We have investigated the molecular anatomy of the herpes simplex virus replicative intermediates by cleavage with the restriction endonuclease BglII. We find that in populations of multiply infected cells, pulse-labeled replicating herpes simplex virus DNA contains at least two and probably all four sequence isomers. Also, it contains no detectable termini. In pulse-chase experiments, we show that endless replicative intermediates are the precursors to virion DNA and that maturation is a relatively slow process. The results are discussed in terms of their significance to possible models of herpes simplex virus DNA replication.
