Zusammenfassung

Inkubation der Seeigelkeime mit14C-Adenin ergab, dass bei reinen Arten der Einbau der markierten Substanz in die RNS von der Mesenchymblastula bis zum Pluteus eindeutig zunimmt. Parallel zur DNS-Synthese verläuft die Zunahme beiParacentrotus undSphaerechinus viel rascher als beiArbacia. Beim Bastard PA nimmt dieser Einbauprozess mit Beginn der morphogenetischen Hemmung (nach ca. 26 h) rasch ab.
