In a search for a region of DNA that will clarify the interordinal relationships we sequenced approximately 1080 nucleotides of the 5' end of the 18S ribosomal RNA gene from representatives ... We ...

The protocol consisted of digestion and two-dimensional electrophoresis of radioactive small-subunit (16S or 18S) ribosomal RNA. When exposed to X-ray film ... Woese and Fox determined the sequences ...

Plant Systematics and Evolution, Vol. 191, No. 3/4 (1994), pp. 171-181 (11 pages) The nuclear-encoded small subunit ribosomal RNA (rRNA) sequences were determined for Genicularia spirotaenia, ...

The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit contains the 16S rRNA, while in eukaryotes, it contains the 18S rRNA. These rRNAs are ... also provide binding ...
