摘要: The rate of synthesis ribosomal RNA varies greatly at different periods development Xenopus laevis eggs and embryos. immature oocyte, which is a single cell, synthesizes many times more than the multicellular early embryo, whereas S-RNA† much intense in embryo oocyte. 28 s 18 are synthesized co-ordinated fashion, lending further support to idea that these molecules not only have common genetic origin but also their under regulation.
