Localization by situ hybridization of amplified ribosomal DNA during Xenopus laevis oocyte maturation (a light and electron microscopy study).
The presence of ribosomal DNA has been demonstrated, by light and electron microscopy study of in situ hybridization with 125I-labeled ribosomal RNA, in the Feulgen-positive bodies which appear during maturation in the cytoplasm of Xenopus laevis oocytes. The ultrastructure of these bodies is described.
