Distinguishing Characteristics between Bacteria and Archaea
What characteristics distinguish Bacteria from Archaea?
Which of the following statements is true?
A. Organisms in the domain Archaea have cell walls, and those in the domain Bacteria do not.
B. Organisms in the domain Bacteria have nuclei, and those in the domain Archaea do not.
C. Organisms in the domain Bacteria are prokaryotes, and those in the domain Archaea are eukaryotes.
D. The DNA sequences of Archaea genes are more similar to eukaryotes than to bacteria.
E. Organisms in the domain Archaea are more likely than those in the domain Bacteria to be disease-causing pathogens.
Final Answer
Bacteria and Archaea differ in terms of cell walls, prokaryotic nature, and DNA sequences.
The characteristics that distinguish Bacteria from Archaea are:
1. Cell Walls: Organisms in the domain Bacteria have cell walls, while those in the domain Archaea may or may not have cell walls.
2. Prokaryotic Nature: Organisms in the domain Bacteria are prokaryotes, meaning they lack a true nucleus, while those in the domain Archaea are also prokaryotes but have distinct characteristics separate from Bacteria.
3. DNA Sequences: The DNA sequences of Archaea genes are actually more similar to Bacteria than to eukaryotes, thus indicating a closer relationship between Archaea and Bacteria.
