Although Chargaff used DNA from both prokaryotic and eukaryotic organisms, there are several differences between the DNA in prokaryotes (like the bacteria Escherichia coli) and eukaryotes (like
turtles). Which of the following accurately describes one of these differences?
A. Prokaryotic cells only contain adenine and thymine, but no guanine and cytosine.
B. Prokaryotic cells contain circular DNA molecules called plasmids.
C. Eukaryotic cells have less DNA, and therefore fewer genes than prokaryotic cells.
D. Eukaryotic DNA is double stranded and prokaryotic DNA is single stranded.
