title: Development of nucleoside phosphotransferase activity in the cerebral hemispheres of embryonal and adult chick.
abstract: In the cerebral hemispheres of the chick embryo, the level of nucleoside phosphotransferase activity is much higher than that of thymidine kinase and it increases progressively during development up to the adult stage. Therefore nucleoside phosphotransferase is not coupled with DNA synthesis.
