Chapter 21, Problem 4TYU

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 Speeles: chimpanzce (Q, orangutan (()), gorllla (G), rhesus macaque (R), mouse (M), and human (H). These segments contain all of the amino acid differences helween the FOXP2 proteinsof these species.

Chapter 21, Problem 4TYU, DRAW IT Below are the amino acid sequences(using the single-letter code; see Figure 5.14) of four

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

(a) The C, G, R sequences are identical. Identily which lines correspond to those sequences.
(b) The O sequence differs from the C, G, R speieces at two amino acids. Underilnethetwodlffcrences inthe H sequence.
(c) The O sequence diffen 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 tho O sequence.
(d) In the M sequence,circle the amino acid(s) that differ from the C, G, R sequence, and draw a square around those that differ from the H sequence.
(e) Primates and rodents diverged between 60 and IO0 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?
