Abstract

Sequences of the polynucleotide chains of RNA found in the large and small ribosomal subunits of rabbit reticulocytes have been determined from the 3′-end by use of periodate oxidation and condensation with [3H]isoniazid and by stepwise degradation. By these methods the hexanucleotide sequences have been found as -pGpUpUpUpGpU for the 28S RNA and -pGpUpCpGpCpU for the 6S RNA of the large ribosomal subunit and the octanucleotide sequence -pGpApUpCpApUpUpA for the 18S rRNA of the small ribosomal subunit. These sequences are present in at least 70% of all the RNA molecules and are discussed in relation to the specific cleavage of rRNA from its precursors and the role of multiple cistrons for rRNA in the DNA of higher organisms. The feasibility of using the method for longer sequence determinations is discussed.
