13. Other proteins can be used to establish degrees of evolutionary relatedness between organisms. Would you expect to find roughly the same number of differences in the
amino acid chains of these other proteins, when comparing organisms? Explain your
answer.

How can proteins be used to compare how closely related species are, and how?

- By comparing the amino acid sequence, as related organisms have similar DNA sequences and so similar amino acid sequences in their proteins.
