摘要：

Previous work has shown that purified DNA serves as a template for replication when injected into frogs' eggs. The experiments reported here demonstrate that purified DNA is not replicated when injected into the cytoplasm of oocytes. The results indicate that cytoplasmic DNA polymerase activity appears when oocytes are converted into eggs during the completion of meiosis and that this may be partly responsible for the induction of nuclear DNA synthesis which follows fertilization. © 1969.
