Use a highlighter to color any amino acid that varies among the species. (Color that amino acid in all sequences.)
c. The O sequence differs from the C, G, R sequences at one amino acid (having V instead of A) and from the H sequence at three amino acids. Identify the O sequence.

Two eukaryotic proteins have one domain in common but are otherwise very different. Which of the following processes is most likely to have contributed to this similarity?

a. Gene duplication

b. Alternative splicing

c. Exon shuffling

d. Random point mutations

Use a highlighter to color any amino acid that varies among the species. (Color that amino acid in all sequences.)

a. The C, G, R sequences are identical. Identify which lines correspond to those sequences.

Use a highlighter to color any amino acid that varies among the species. (Color that amino acid in all sequences.)

b. The H sequence differs from that of the C, G, R species at two amino acids. Underline the two differences in the H sequence.

Use a highlighter to color any amino acid that varies among the species. (Color that amino acid in all sequences.)

d. In the M sequence, circle the amino acid(s) that differ from the C, G, R sequences, and draw a square around those that differ from the H sequence.

Use a highlighter to color any amino acid that varies among the species. (Color that amino acid in all sequences.)

e. Primates and rodents diverged between 60 and 100 million years ago, and chimpanzees and humans about 6 million years ago. Compare the amino acid differences between the mouse and the C, G, R species with those between the human and the C, G, R species. What can you conclude?
