Fluorescence Photoactivation and Dissipation (FPD),ns of fluorescence methods has been expanded broadly by the development and availability of fluorescent molecules with specifically tailored characteristics. The attachment of these fluorescent molecules to molecular species has become a powerful approach for investigating the structure and dynamics of complex systems.

A Pool of Soluble Nuclear Lamins in Eggs and Embryos of ,, ca. 4 hours after fertilization (7). Recent experiments indicate that Xenopus eggs also contain stored nuclear envelope components (8, 9). When chromatin or purified DNA are injected into eggs or incubated in extracts of activated eggs nucleus-like structures are assembled possessing nuclear pores and a nuclear lamina.

Uptake of Oocyte Nuclear Proteins by Nuclei of , Embryos,breakdown leads to the loss of a compartment for the nuclear proteins (3, 4). They are distributed in the cytoplasm of the mature egg, mainly in the animal hemisphere where later in development most of the nuclei of the embryo will appear (3, 4). After fertilization, these proteins are reaccumulated by the newly generated nuclei of the embryo.

It is likely that a number of questions relating to this process, particularly those that involve the identification and characterization of specific exchange sites, can be answered by utilizing electron-opaque tracers.
