Comment: “This sequence is the 16S ribosome unit -~1541 bases. Carl Woese originally worked on the ribosome to find conserved sequences common across all species on earth and so it was thought important to obtain a generic GGF motif from part of the ribosome. The image ,although from the 70s unit is thought to be typical of the 16S unit as well in terms of a generic unit. Complete nucleotide sequence of a 16S ribosomal RNA gene from Escherichia coli Proc.
