The content, biosynthesis and template activity of poly(A) + RNA in the early stages of sea urchin development have been studied. The amount of poly(A) + RNA reaches a maximum at the middle blastula stage in polyribosomes and at the 8‐blastomere stage in the cytoplasm. Poly(A) + RNA synthesis becomes noticeable at the 64‐blastomere stage and the spectrum of newly synthesized molecules is different from that at the middle blastula stage. The products of translation in vitro of poly(A) + RNA at all the stages studied show insignificant differences and contain a major group of polypeptides of molecular mass 10–20 kDa.
