Chapter 22, Problem 13TYK

When cytochrome c molecules are compared, yeasts and molds are found to differ by approximately 46 amino acids per 100 residues (amino acids in the protein); insects and vertebrates are found to differ by 29 amino acids per 100 residues. What can one conclude from these data?

  1. a. Very little, unless the DNA sequences for the cytochrome c genes are compared.
  2. b. Insects and vertebrates diverged from a common ancestor more recently than did yeasts and molds.
  3. c. Yeasts and molds diverged from a common ancestor more recently than did insects and vertebrates.
  4. d. The evolution of cytochrome c occurred more rapidly in yeasts and molds than in insects and vertebrates.

Scientists conducted research to examine the evolutionary relationship between 10 bird species and an alligator species. They isolated the amounts of the dinucleotides cytosine and guanine found in the genomic DNA of each species. The graph shows the traditional taxonomic groups of the bird species used and the average percentage of dinucleotides in their DNA.   Which of the following statements is best supported by the DNA evidence? A - Gamebirds likely evolved after non-perching birds.   B - A bird’s ability to fly may be linked to its dinucleotide percentage.   C - The dinucleotide percentages demonstrate coevolution of all species.   D - Non-perching birds are more similar genetically to alligators than flightless birds.
A group of scientists was examining the amino acid sequence for the gene c-FLIP, which is present in most vertebrates. The image shows the amino acid sequence for a variety of different vertebrate species.     What conclusions would the scientists draw from this sequence? A. This protein is a derived feature, evolving multiple times. B. This protein is a primitive feature, present in basal vertebrates. C. The sequence of this protein is nearly identical in lampreys and humans. D. The sequence of this protein is not conserved between turkeys and chickens.
A cladogram shows the evolutionary relationship between humans, chimpanzees, and gorillas. The cladogram currently shows humans and chimpanzees with a more recent common ancestor compared to gorillas. Which piece of evidence, if true, would most likely weaken this hypothesis? Amino acid analysis of the cytochrome shows significant differences in the sequence of amino acids between humans and goriffas. DNA sequence analysis of the hemoglobin alpha gene shows that humans and chimpanzees have a more similar sequence to each other than they do to the gorilla's DNA sequence. The cells of the eye in embryos of gorillas and humans follow a similar pattern of development chimpanzee embryos are different Fossils of humans appear in deeper sedimentary rock layers compared to fossils of chimpanzees.
