Possible labelings of selected motifs (a) The two possible labelings with one mutation of the tata-motif imply that the mutation occurred before the speciation event. (b) Two out of three labelings of the actg- motif imply a mutation event before the speciation event. Only the labelings with nucleotide a as an ancestor are shown, the 3 other cases are similar. (c) Four of the five possible labelings of the acat-motif tree contain a mutation event before the speciation event.
