title: [Nuclear RNA polymerase activity of L929 cells producing interferon in the presence of sera from adult and newborn mice].
abstract: A study was made of the kinetics of interferon production and nuclear RNA-polymerase activities of L929 cells producing interferon in the presence of serum from adult and newborn mice. It was shown that RNA-polymerase activities of the nuclei were similar in both the cases. The results indicate that the low level of interferon production in the presence of newborn mouse serum is not determined by alterations in transcription.
