    Notes: Summary Annulate lamellae (AL) were found in preblastoderm cytoplasm and nuclei of the giant milkweed bug,Oncopeltus fasciatus. To the best of the authors' knowledge, this is the first report of such an occurrence among the insects. Cytoplasmic AL were scattered about the nucleus during early prophase and then accumulated during late prophase to form two dome-shaped arrays lying opposite each other with the nucleus interposed. Also, intranuclear annulate lamellae were found as single strands or vesicles within the nucleus during prophase.

    Description / Table of Contents: Zusammenfassung Ein vereinfachter Mechanismus derRNA-Replikation durch eine spezifische Polymerase wird durch direkte numerische Integration und mit Hilfe der Annahme von „Quasigleichgewicht“ analysiert. Die Quasigleichgewichtsannahme wird an Hand von drei Beispielen einfacher Zweistufenreaktionen mathematisch definiert. Die drei Beispiele beschreiben: (1) die Annäherung an den Gleichgewichtszustand, (2) den irreversiblen Abbau und (3) das unbeschränkte Wachstum einer Verbindung.
    Notes: Abstract A simplified mechanism ofRNA-replication by a specific polymerase is analysed by direct numerical integration and by means of the “quasiequilibrium approximation”. The quasiequilibrium approximation is formulated in precise mathematical terms for three simple, two step reactions which describe approach towards equilibrium, irreversible transformation and unlimited growth.
