A method for comparing DNA base sequences by comparing similarities between two amino acid sequences translated from two DNA base sequences, respectively, includes (1) a step of dividing each of the first DNA base sequence and the second DNA base sequence into groups of successive three nucleotides each, translating each of these groups of nucleotides into an amino acid, and thereby obtaining a first amino acid sequence and a second amino acid sequence, and (2) a step of determining similarities between each amino acid of the first translated amino acid sequence and each amino acid of the second translated amino acid sequence in view of nucleotide insertions or deletions in the first and second DNA base sequence and amino acid insertions or deletions in the first and second translated amino acid sequence. The method is repeated by shifting the base sequences one base at a time.
A method of comparing DNA base sequences between a first DNA base sequence having at least a first base, a second base, a third base, a fourth base, a fifth base and a sixth base in a direction toward 3′-end and a second DNA base sequence having at least a first base, a second base, a third base, a fourth base, a fifth base and a sixth base in a direction toward 3′-end comparing the steps of:
