Imagine that you discovered the following information about the three domains of life:
Feature Bacteria Archaea Eukaryotes
RNA polymerase small, simple complex complex
Introns absent present present
Antibiotic sensitivity sensitive insensitive insensitive
Membrane Lipids C chains unbranched C chains branched C chains branched
These data would support which of the following conclusions?
A) Eukaryotes share a more recent common ancestor with bacteria than with archaea.
B) Bacteria are the only one of the three groups that lacks a nucleus.
C) Archaea are more similar to bacteria than to eukaryotes.
D) Eukaryotes are more similar to archaea than to bacteria.

Question

Quizplus · Accepted Answer

The similarities between archaea and eukaryotes, such as complex RNA polymerase, presence of introns, insensitivity to antibiotics, and branched membrane lipids, suggest that eukaryotes are more similar to archaea than to bacteria.
