Why have some microbiologists proposed using ribosomal RNA as the basis for defining bacterial species?
A) Bacteria are not interbreeding populations, and ribosomal RNAs are highly conserved genes present in all prokaryotes.
B) Ribosomal RNAs are highly conserved genetic sequences present in all prokaryotes.
C) Ribosomal RNA is the basis for domain assignment.
D) Bacteria vary too little in their physical and biochemical traits.
E) The "interbreeding population" criterion does not apply to bacteria.
