Functional Organization of the Amphibian Oocyte Nucleusis by gel electrophoresis or electron microscopic spreading methods. In addition, the size of amphibian oocyte nuclei greatly facilitates the introduction of certain substances by microinjection. In fact, Xenopus oocytes are presently used in numerous laboratories as “living test tubes” to study the十字架 发表于 2025-3-29 03:31:06
Informational Content of the Echinoderm Egg during early embryonic development. Compelling evidence for the extensive utilization of stored maternal mRNA was developed, and the cytoplasmic informational molecules defined by the earlier experimental embryologists are frequently thought to include stored mRNAs.

John H. Postlethwait,Franco Giorgister prisms in a standard cavity configuration. Figure 1 shows the relevant spectroscopy. We choose R-800 because it has the longest wavelength emission of the high-quantum efficiency family of rhodamine dyes; this may represent the longest wavelength attainable for CW-pumped CPM dye lasers. We find
