the existence of complementary sequences in 5s rrna and small ribosomal subunit rna , along with the previous observation that there is very efficient and selective hybridization in vitro between 5s and 18s rrna , suggests that base-pairing between 5s rrna in the large ribosomal subunit and 18s ( 16s ) rrna in the small ribosomal subunit might be involved in the reversible association of ribosomal subunits .
