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.
