BackWhereas the first edition of Bergey’s Manual relied on morphological and biochemical characteristics to classify microbes, the new edition focuses on ribosomal RNA sequences. List several other criteria for grouping and classifying bacteria.

a. The cell is a prokaryote.
b. The cell is a fungus or yeast.
c. The cell is an archaea.
d. The cell is not a pathogen.
e. The cell is in Domain Archaea.
