You have a microorganism, and you have identified the components below. Which of these components tells you that you have a an a
rchaeon, rather than a bacterium? a. 705 ribosomes
b. Single circular chromosome
c. Plasmids
d. Presence of N-acetyltalosaminuronic acid in the cell wall
The correct answer is d. Presence of N-acetyltalosaminuronic acid in the cell wall.
Explanation:
Bacterial cell wall is made up of peptidoglycan which contains NAG and NAM units joined together by β(1-4) glycosidic linkage but the cell wall of archaea are different from the bacteria and called pseudo-peptidoglycan.
The cell wall of archaea is also called pseudomurein which is also composed of two units, N-acetylglucosamine and N-acetyltalosaminuronic acid and these two components are joined together by β (1-3) glycosidic linkage which is different from linkage in bacteria.
Therefore the correct answer is d. Presence of N-acetyltalosaminuronic acid in the cell wall.
