“…Hence, no single similarity table, be it the Clustal Omega approach, or the Four-color map approach, has claims to be "the solution" when it comes to similarity studies of biological objects. Clustal Omega approach 67 may have here an advantage because it compares bio-sequences that have been aligned. However, in view that the protein alignment problem and the related DNA alignment problems finally have been exactly solved using a very efficient algorithm, this open a novel direction in protein and DNA similarity studies.…”
