title: Effects of cordycepin on the synthesis of nuclear and cytoplasmic RNAs in embryonic cells of Xenopus laevis.
abstract: Effects of cordycepin on the incorporation of [3H] guanosine into embryonic Xenopus cells were examined. Cordycepin inhibited the labeling not only of poly(A) + RNA, but of all the other major classes of RNAs. Cellular fractionation showed that this inhibition was much stronger in the labeling of cytoplasmic RNAs than of nuclear RNAs. [3H]Cordycepin was incorporated into both poly(A) + RNA and other RNA species.
