Answer and Explanation:
Because the DNA sequence determines a protein's amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That's because closely related species most likely diverged from one another fairly recently in the evolutionary span. Thus, they haven't had as much time to accumulate random mutations in their genetic codes.
Answer: Purpose
Explanation: If you have no purpose or inclination to have a hypothesis, you wouldn't have a hypothesis in the first place. Plus, it can't be experiment because there isn't anything to experiment without a hypothesis. The analysis is, well analyzing your data to see if your hypothesis is realistic. Definitely, not conclusion. <span />
