Imagine that you are a marine biologist. As part of your exploration, you dredge up an unknown animal species from the seafloor. Describe some of the characteristics you should look at to determine the phylum to which the creature should be assigned.
Name the five (5) sources of data used to reconstruct phylogenies.
Choose the correct statements about proteins and evolution. Select all that apply.A. Two proteins that have similar tertiary structure are said to be homologous.B. The tertiary structure of a protein is more conserved than the primary structure.C. Lupine leghemoglobin and human α-hemoglobin are only about 16% identical. This is an example of divergent evolution.D. Orthologs are derived from a common ancestor, but often have different functions.E. Percent identity for a random alignment of two nucleic acids is likely to be lower than the percent identity for an equal-length random alignment of two polypeptide segments.
Are domain and kingdoms the same? Explain.
What is a domain? What are the three domains of life?
Distinguish phylogeny from taxonomy and list one example where each is used.
Why is the sequence similarity generally higher when comparing two globins from mammals than when comparing a globin from a mammal and a globin from a plant?
Compare and contrast plant and animal cells.
List three main differences between Bacteria and Archaea.
Based on the phylogeny shown below, which of the following statements about taxon relationships is not supported?A. Humans are more closely related to bats than they are to iguanas.B.
