Choose the correct statements about proteins and evolution. a. Percent identity for a random alignment of two nucleic acids is likely to be higher than the percent identity for an equal-length random alignment of two polypeptide segments. b. Paralogs are derived from a common ancestor but often have different functions. c. Two proteins that have similar tertiary structures are said to be homologous. d. The tertiary structure of a protein is less conserved than the primary structure. e. Lupine leghemoglobin and human a-hemoglobin are only about 16% identical. This is an example of convergent evolution.
