Question

Which of the following contribute(s) to the differences between the members of the Domain Archaea and the Domain Bacteria?

1) Archaea lack muramic acid.
2) Archaea have isopranyl glycerol ethers rather than fatty acid esters in their membrane lipids.
3) Archaea differ from bacteria in their tRNA composition, ribosome structure, and antibiotic sensitivity.
4) All of the choices are correct.

Answer 1

Archaea differ from bacteria in their tRNA composition, ribosome structure, and antibiotic sensitivity.

Step-by-step explanation:

Archaea and Bacteria have several differences:

1. The cell walls of Archaea lack peptidoglycan, which is present in Bacteria.
2. The plasma membranes of Archaea are composed of phytanyl groups, while in Bacteria they are made up of fatty acids.
3. Archaea have different tRNA composition, ribosome structure, and antibiotic sensitivity compared to Bacteria.

Therefore, option 3) Archaea differ from bacteria in their tRNA composition, ribosome structure, and antibiotic sensitivity is correct.
