A researcher has discovered an unusual organism deep in the crust of Earth. She wants to know whether it is prokaryotic or eukaryotic. Imagine that she has rapid tests to determine whether the following molecules are present: DNA, RNA, and the proteins that form microtubules. Which test would you advise her to use and why?

    Test for RNA, because only eukaryotes have ribosomes.
    Test for DNA, because only eukaryotes have a nucleus.
    Test for microtubule proteins, because only eukaryotes have microtubules.
