摘要：

A direct comparison was made between the DNA polymerase activity of isolated nuclei and the sea urchin embryos from which they were derived. The nuclei, which were isolated by simple aqueous techniques, contained 56 to 95% of the total DNA polymerase activity of the hatched embryos. It is concluded that sea urchin embryo DNA polymerase, an enzyme preferentially primed by native DNA, is strongly associated with nuclei at the stage of hatching, a period of rapid DNA synthesis. © 1969.
