Abstract
Current theory is adequate to the task of finding an optimal alignment between two character strings such as nucleic acids. Most algorithms currently in use must fail to find the homologous alignment between a set of codons for the chicken α- and β-hemoglobin sequence when it is in fact discoverable by a more general treatment of gaps. Fundamental reasons for this are discussed.
Keywords: chicken hemoglobin; homology-analogy; distance similarity; gap weighting; Sellers, Needleman-Wunsch algorithms
