Abstract
The three types of archaebacterial ribosomal RNAs, 5S, 16S, and 23S, have b een studied in terms of their closest homologues of the non-archaebacterial origin, the numbers of close homologues of eukaryotic and eubacterial orga nisms, and the insertion and deletion of bases. It is concluded that all th e ribosomal RNAs are of eubacterial-type. In contrast, archaebacterial ribo somal proteins have been identified to compose a population that possesses characteristics of eukaryotic-type. Thus the archaebacterial ribosome is a chimera of the eubacterial-type RNAs and the eukaryotic-type proteins.
