- <p>In bioinformatics, BLAST (Basic Local Alignment Search Tool) is an algorithm
- for comparing primary biological sequence information, such as the amino-acid
- sequences of different proteins or the nucleotides of DNA sequences. A BLAST
- search enables a researcher to compare a query sequence with a library or
- database of sequences, and identify library sequences that resemble the query
- sequence above a certain threshold. Different types of BLASTs are available
- according to the query sequences. For example, following the discovery of a
- previously unknown gene in the mouse, a scientist will typically perform a
- BLAST search of the human genome to see if humans carry a similar gene;
- BLAST will identify sequences in the human genome that resemble the mouse
- gene based on similarity of sequence.</p>

- <h2> BLAST Search </h2>
- <p>
- Search for one or more of your sequences (using BLAST). First pick
- a query type (nucleotide or protein). You will be able to set search
- parameters on the next page. Choose the appropriate program based on the Query type and Target
- database type. Please click on the program name to view the search form.
