Evidence for similarities between Archaea and Eukarya includes the
A) absence of introns from genes in both groups.
B) fact that both contain circular DNA without histones.
C) presence of peptidoglycan in the cell walls of both groups.
D) fact that both have several kinds of relatively complex RNA polymerases.

Question

Quizplus · Accepted Answer

The fact that both Archaea and Eukarya have several kinds of relatively complex RNA polymerases is evidence for similarities between them. This suggests that they share a common ancestor and have undergone similar evolutionary processes. The absence of introns from genes in both groups is a similarity, but this is not as strong evidence as the presence of complex RNA polymerases. The fact that both contain circular DNA without histones is a similarity, but this is a characteristic of only some Archaea, not all. The presence of peptidoglycan in the cell walls of both groups is not accurate, as only some Archaea have this feature.
