Yeast RNA prepared by the method of Clarke and Sehryver, whose molecular weight is about 20,000, was fractionated by the use of an ion-exchange resin, Dowex-2 chloride form. Elution was carried out by the stepwise increase in the concentration of sodium chloride up to 5M. Differences in molecular weight, which was determined by the surface film method, but not in nucleotide composition were found among the fractions thus obtained. It was suggested that the molecular size of a fraction determines the ease with which it was eluted by different concentrations of salt. By this method and with this preparation of RNA, we have been unable to obtain the RNA fractions with different nueleotide compositions. Then, cellulose treated with epiehlorohydrin and triethanolamine (ECTEOLA) was tested as an ion-exchanger for fractionating RNA. The results obtained were essentially same as in the case of Dowex-2, but the adsorption of RNA on ECTEOLA adsorbent and the recovery of the eluted RNA from it were a little better than in the case of the resin. Recently, it has been found in our laboratory that highly polymerized RNA can be precipitated from neutral aqueous solution by high concentration of sodiun chloride or by relatively low concentration of magnesium chloride. Highly polymerized yeast RNA prepared by the method of Crest field, Smith, and Allen was fractionated by the precipitation with neutral salts. The fraction soluble in the concentrated salt solution was rich in its guanine and cytosine contents. It seemed that the easily precipitable fraction had higher molecular weight than the soluble one.
