To determine:
The reason that some scientists consider that archaea is more closely related to eukaryotes than they are to the other prokaryotes.
Introduction:
Archaea share some common features with bacteria such as presence of 70S ribosomes, fibrous cytoskeleton, circular DNA, and lack of membranous organelles but they both differ on the basis of cytoplasm.
