  1. *Nucleotides (A, T, G, or C) are represented by P or Q.
  2. **In 12 of the 13 cases, substitution occurred in one of the four sequences. In one case, substitution occurred in two of the four sequences into different nucleotides.
  3. ***The lengths are not identical among the four sequences because of insertions/deletions.
