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.

DRAW IT Below are the amino acid sequences (using single letters; see Figure 5.14) of three short segments of the FOXP2 protein from five species. These segments contain all amino acid differences between the FOXP2 proteins of these species. Compare the amino acid sequences by answering parts (a)–(d).Chimpanzee PKSSD ... TSSTT ... NARRDMouse PKSSE ... TSSTT ... NARRDGorilla PKSSD ... TSSTT ... NARRDHuman PKSSD ... TSSNT ... SARRDRhesus monkey PKSSD ... TSSTT ... NARRD(a)Circle the names of any species that have identical amino acid sequences for the FOXP2 protein.

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?

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.)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.

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.

DRAW IT Below are the amino acid sequences (using the single-letter code; see Figure 5.14) of four short segments of the FOXP2 protein from six species: chimpanzee (C), orangutan (O), gorilla (G), rhesus macaque (R), mouse (M), and human (H). These segments contain all of the amino acid differences between the FOXP2 proteins of these species.
