Basic Local Alignment and Search Tool
Tutorial and training materials by OpenHelix
|Learn to use BLAST, (Basic Local Alignment and Search Tool), the sequence similarity searching tool from the National Center for Biotechnology Information (NCBI) at NIH. You can use BLAST to find sequences similar to your nucleotide or protein sequences. There are also a variety of specialized BLAST programs available, including Primer-BLAST, VecScreen, SNP BLAST options, multiple alignment tools, and more. You can easily compare 2 sequences to each other. These can provide invaluable information in your quest to infer functional and taxonomic relationships for known or unknown sequences, or to further design experiments.|

More about the resource:
BLAST is a key resource developed and supported by the National Center for Biotechnology Information (NCBI). Sequence submissions from around the world help to populate NCBI's Genbank database, to which novel sequences can be compared using BLAST. BLAST results are linked to the vast NCBI Entrez network of databases allowing for a rich resource for discovery.
