[Properties of the RNA-component informosome from amphibian oocytes].
RNA synthesis in in vivo ovulated oocytes of Rana temporaria frog was studied. It was shown that RNA synthesised during oocyte maturation is non-mitochondrial and is localized mostly in the ribonucleoprotein fraction; the bulk of the RNA is present in informosomes. The RNA extracted from informosomes shows a heterogeneous sedimentative distribution with predominant components of 19S and 26-27S. This RNA does not adsorb on oligo(dT)-cellulose columns.
