Basic Local Alignment Search Tool (BLAST) for bioinformatics

WebIf there is no similarity, no alignment will be returned. Local alignments algorithms (such as BLAST) are most often used. A global alignment should only be used on sequences that share significant similarity over most of their extents, and then it will sometimes return a better presentation. An example is the alignment of NP_004013 with NP_004014. WebBLAST Similarity Search.
