title: [Autoradiographic study of ribosomal RNA metabolism during mitosis in the myxomycete Physarum polycephalum].
abstract: In Physarum polycephalum, the study of RNA metabolism just after metaphasis shows an important 3H-uridine incorporation. Most of the labelling is found in the nucleolus when we can see it again during interphasis. Therefore a ribosomal RNA synthesis does exist before any visible nucleolar structure.
