A BLASTsearch enables a researcher to compare a query sequence with a library ordatabase of sequences, and identify library sequences that resemble the querysequence above a certain threshold. Different types of BLASTs are availableaccording to the query sequences. For example, following the discovery of apreviously unknown gene in the mouse, a scientist will typically perform aBLAST search of the human genome to see if humans carry a similar gene;BLAST will identify sequences in the human genome that resemble the mousegene based on similarity of sequence.</p><blockquote>Altschul,S.F., Gish,W., Miller,W., Myers,E.W. and Lipman,D.J.

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.
