BLAST is an acronym for basic local alignment search tool; the BLAST family of database search programs takes as input a query DNA or protein sequence, and search DNA or protein sequence databases for similarities that may indicate homology. The programs implement variations of the BLAST algorithm, which is a heuristic method for rapidly finding local alignments with scores sufficiently high to be statistically significant.
