  • Title: RNA and protein in nucleolar structures of dragonfly oocytes.
    Author: Halkka L, Halkka O.
    Journal: Science; 1968 Nov 15; 162(3855):803-5. PubMed ID: 5686219.
    Abstract:
    Dragonfly and damselfly oocytes regularly contain two nucleolus like bodies of different sizes, a primary nucleolus and a secondary nucleolus. The primary nucleolus stains more deeply with RNA stains than with an arginine stain; the seconidary nuicleolus stains conzversely. The primary nulcleolus incorporates uridine under all conditions tested; the secondary, only after precautions have been taken to preserve soluble RNA. Both inicorporate lysine.
