The DNA sequences of human beings and chimpanzees are approximately 99 percent alike. What might explain the seemingly large differences that exist between these two closely related organisms?

Question

Quizplus · Accepted Answer

The differences in gene expression between humans and chimpanzees can lead to significant differences in the way their genomes function, even though their DNA sequences are very similar. This may explain many of the observable differences between the two organisms. The other options are incorrect, since chimpanzees do use DNA as their genetic material, have introns in their DNA, and are also eukaryotic like humans.
