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 ...
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 ...
Three different types of RNA polymerase exist in eukaryotic cells, whereas bacteria have only one. In eukaryotes, RNA pol I transcribes the genes that encode most of the ribosomal RNAs (rRNAs ...
Only recently has the ribosome—one of the oldest molecular machines in evolutionary terms—been recognized as an active ...
