A researcher is comparing the sequences of genes encoding cell wall proteins in archaeons with those coding cell wall proteins in bacteria. How similar do you expect these sequences will be?
A)These sequences will be similar, as both archaeons and bacteria have cell walls composed of peptidoglycan variants.
B)These sequences will be dissimilar, as archaeons have chitin-based cell walls and bacteria primarily have peptidoglycan-based cell walls.
C)These sequences will be dissimilar, as archaeon cell walls are not composed of peptidoglycan.
D)These sequences will be similar, as bacteria and archaeons belong to the same prokaryotic domain.

Question

Quizplus · Accepted Answer

Archaeon cell walls are not composed of peptidoglycan, which is a characteristic feature of bacterial cell walls. Therefore, the sequences of genes encoding cell wall proteins in archaeons would be dissimilar to those in bacteria.
