(c)In the human sequence, underline any amino acid that differs from the sequence for the chimpanzee, gorilla, and rhesus monkey.

Which of the following best describes the experimental evidence that the FOXP2 gene is vital to the normal development of vocalization in vertebrates and yet has evolved among different vertebrate lineages?

The advantage of copy-number variants (CNVs) over SNPs in human genomic studies is that CNVs __________.

Bioinformatics includes(A)using DNA technology to clone genes.(B)using computer programs to align DNA sequences.(C)using a person's genomic sequence to inform decisions about medical treatment.(D)amplifying DNA segments from a species' genome.

(d)Primates and rodents diverged about 65 million years ago, and chimpanzees and humans diverged about 6 million years ago (see Figure 21.17). How many amino acid differences are there between the sequence for the mouse and the sequence for the chimpanzee, gorilla, and rhesus monkey? How many amino acid differences are there between the human se-quence and the sequence for the chimpanzee, gorilla, and rhesus monkey? Based solely on the numbers of amino acid differences occurring over these time periods, what might you hypothesize about the rate of evolution of the FOXP2gene? Based on the information in the chapter regarding the FOXP2 gene, is your hypothesis correct?

(b)In the sequence for the mouse, circle any amino acid that differs from the sequence for the chimpanzee, gorilla, and rhesus monkey. Then draw a box around any amino acid that differs from the human sequence.

Bioinformatics includes all of the following excepta. using computer programs to align DNA sequences.b. using DNA technology to combine DNA from two different sources in a test tube.c. developing computer-based tools for genome analysis.d.using mathematical tools to make sense of biological systems.
