Abstract

The sequence complexity of sea urchin embryo micromere RNA is about 75% of that of total 16-cell embryo cytoplasmic RNA, as reported earlier by Rodgers and Gross [Rodgers, W. H., and Gross, P. R. (1978) Cell, 14, 279–288]. In contrast to the rest of the embryo, there are few, if any, complex maternal RNA species in the micromere cytoplasm which are not represented in the polysomes. The micromeres do not contain detectable quantities of high-complexity nuclear RNA, though such RNA exists in other cells of the fourth-cleavage embryo.
