Presence of Ribonucleic Acid in the Initial Yolk Globules of Oocytes of Aplysla depilans L.

Naturevolume 199page697 (1963) | Download Citation



PREVIOUS work carried out with the electron microscope has indicated that the formation of yolk globules of some species of Mollusca and Echinodermata occurs by aggregation of protein particles1,2. Experiments have also indicated the possibility of obtaining in neoplastic cells an artificial aggregation of the particles1–3. Work on oocytes has shown the ribosomal nature of the particles, and it is thus possible that RNA is present in the product of protein synthesis.
