[Protein granules and spheres in the nuclei of reptile oocytes].
The morphology, the time and place of formation of the protein granules and spheres in nuclei of reptiles 11 species of oocytes are described. The problem of the place of protein synthesis forming the granules and spheres is discussed. Examples are cited showing presence of protein bodies in nuclei of primary sex cell, oogonies, spermatocytes, and in macronuclei of protozoa as well as in oocytes at the diplotene state of some invertebrae and vertebrae. The description of their chemical composition and ultrastructure is given. With regard to the nucleus programming role. the significance of these structures for accumulation of proteins necessary for meiotic division and cleavage of oocytes, was suggested.
