BLAST - Basic Local Alignment Search Tool
In bioinformatics, Basic Local Alignment Search Tool, or BLAST, is an algorithm for comparing primary biological sequence information, such as the amino-acid sequences of different proteins or the nucleotides of DNA sequences. Three basic forms are available:
- BLAST - protein sequences.
- BLASTN - nucleotide sequences.
- BLASTX - translated nucleotide sequences.
