Intermolecular base-paired interaction between complementary sequences present near the 3' ends of 5S rRNA and 18S (16S) rRNA might be involved in the reversible association of ribosomal subunits.

abstract：:The primary rRNA transcript contains a large external transcribed spacer (ETS) approximately 4,000 nucleotides in length. We have used subcloned DNA probes derived from the 5' end of the ETS in conjunction with Northern blot analysis of murine nuclear RNA to examine processing of this region. In agreement with the res...
