WebExamples. GreedyMotifSearch, starts by setting best_motifs equal to the first k-mer from each string in Dna (each row assign a k-mer), then ranges over all possible k-mers in dna[0], the algorithm then builds a profile matrix Profile fro this lone k-mer, and sets Motifs[1] equal to the profile_most_probable k-mer in dna[1].
