BLAST

Basic Local Alignment Search Tool. A nucleic acid- and protein-sequence comparison algorithm which is used to find matches in gene sequences and to search sequence databases for optimal local alignments to a query sequence.

BLAST uses a heuristic algorithm, seeking local alignments and creating a matrix of similarity scores for all possible pairs of residues, defining high-scoring segments, statistically evaluating the significance of the results and detecting relationships among sequences which share only isolated regions of similarity.
