Evolutionary relationships between proteins can be identified through a substitution matrix, which scores the replacement of one amino acid with another amino acid. A large positive score in a substitution matrix indicates that a substitution occurs frequently. 1) Select the amino acids that never yield a positive score in a substitution matrix. valine proline glycine arginine cysteine 2) What feature prevents these amino acids from yielding a positive score in a substitution matrix? They exhibit unique features compared to other...
