Question

Which of the following can differentiated Archaea and Eubacteria?

• A. Cell wall component
• B. Absence or presence of nuclear membrane
• C. Absence or presence of rRNA
• D. Absence or presence of cell membrane

Answer 1

The correct option is A Cell wall component

Archaea and eubacteria both are the domains of prokaryotes. They have a disorganized nucleus and they are devoid of membrane-bounded organelles. The major difference between them is cell wall structure. Bacteria have peptidoglycans (murein) in cell walls and archaea do not have peptidoglycans but instead have pseudomurein in their cell walls.

Thus, the correct answer is option A.
