Despite ether-linked lipids being a hallmark of the Archaea, the thermophilic sulfate-reducing bacteria in ________ also contain ether-linked lipids, which suggests they may be more closely related to Archaea than many other groups in Bacteria.
A) Aquifex
B) Thermodesulfobacterium
C) Thermus
D) Verrucomicrobium

Question

Quizplus · Accepted Answer

The statement in the question suggests that thermophilic sulfate-reducing bacteria in Thermodesulfobacterium contain ether-linked lipids, which is a characteristic of Archaea. This suggests that Thermodesulfobacterium may be more closely related to Archaea than other groups within Bacteria. The other options (Aquifex, Thermus, and Verrucomicrobium) do not have the same evidence linking them to ether-linked lipids and Archaea.
