Recent Biochemical Evidence Divides Organisms into Three Domains

What is the difference between bacteria and archaea?

Archaea have several differences with bacteria such as that archaea have similar metabolic pathways to eukaryotes, also that archaea will contain lipid ethers in cell membranes, and bacteria will not. Archaea will also reproduce asexually and divide by binary fission.

Answer:

The statement that best describes why bacteria and archaea have been placed into separate domains is because they have differences in the biochemical makeup of their cell walls. Therefore, we can confirm that the correct option is C: They have differences in the biochemical makeup of their cell walls.

Recent biochemical evidence divides all organisms into three domains: Bacteria, Archaea, and Eukarya. Previously, Bacteria and Archaea were viewed as one group. The reason why Bacteria and Archaea have been placed into separate domains is due to the differences in the biochemical makeup of their cell walls.

Archaea have unique characteristics that set them apart from bacteria. They have similar metabolic pathways to eukaryotes, contain lipid ethers in cell membranes, and reproduce asexually through binary fission. This distinct biochemical makeup distinguishes them from bacteria, leading to their placement in separate domains.
