Unformatted text preview: ter allowing the mating to proceed for 30 minutes, you select for Pyr+ colonies. Of these colonies, 32% are Met+, 94% are Xyl+, 7% are Tyr+, 59% are Arg+, 0% are His+, and 71% are Mal+. What can you conclude about the order of these genes? order of entry: Pyr+ Xyl+ Mal+ Arg+ Met+ Tyr+ His+ 3) Do you think that each of the following types of mutations would be most likely to have very severe effects, mild effects, or no effect at all? a) Nonsense mutations occurring in the sequences encoding amino acids near the N terminus of the protein severe b) Nonsense mutations occurring in the sequences encoding amino acids near the C terminus of the protein mild c) Frameshift mutations occurring in the sequences encoding amino acids near the N terminus of the protein severe d) Frameshift mutations occurring in the sequences encoding amino acids near the C terminus of the protein mild e) Silent mutations no effect f) Conservative missense mutations mild or no effect g) Nonconservative missense mutations affecting the active site of the protein severe h) Nonconservative missense mutations not in the active site of the protein severe or mild...
