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?

These sequence with not be similar because, the archaeons cell wall lack peptidoglycan.

Explanation:

The peptidoglycan is made up of peptide chain and polysaccharide. They are mostly found on bacterial cell. It gives structure to the organism and provide strength to the outer structure of the organism as well.

The cell wall of most archae are composed of S-layer protein. The cell wall also composed of other sugar proteins like pseudomurein, heteropolysaccharide and methanochondriotin.

In this case, the sequences will be different, simply because of the difference in the composition of their cell walls.
