A mutational event inserts an extra nucleotide pair intoDNA. Which of the following outcomes do you expect?(1) No protein at all; (2) a protein in which one aminoacid is changed; (3) a protein in which three amino acidsare changed; (4) a protein in which two amino acids arechanged; (5) a protein in which most amino acids afterthe site of the insertion are changed.
