3.5: The BLAST algorithm (Basic Local Alignment Search Tool)?

WebBLAT on DNA is designed to quickly find sequences of 95% and greater similarity of length 25 bases or more. It may miss more divergent or shorter sequence alignments. It will find perfect sequence matches of 20 bases. BLAT on proteins finds sequences of 80% and greater similarity of length 20 amino acids or more. WebIdentifying Sequences with BLAST 1 of 3. There are many options on the Standard Nucleotide BLAST page. For example, you can select different databases to search; you can exclude certain data sources; and you can select a specific algorithm by which to search.
