BLAST (biotechnology)
In bioinformatics, BLAST (basic local alignment search tool) is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences. A BLAST search enables a researcher to compare a subject protein or nucleotide sequence (called a query) with a library or database of sequences, and identify database sequences that resemble alphabet above a certain threshold. 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 pig genome that resemble the mouse gene based on similarity of sequence. Background BLAST, which ''The New York Times'' called ''the Google of biological research'', is one of the most widely used bioinformatics programs for sequence searching. It addresses a fundamental problem in bioinformatics ...

Stephen Altschul
Stephen Frank Altschul (born February 28, 1957) is an American mathematician who has designed algorithms that are used in the field of bioinformatics (the Karlin-Altschul algorithm and its successors). Altschul is the co-author of the BLAST algorithm used for sequence analysis of proteins and nucleotides. Education Altschul graduated summa cum laudeNew York Times: "Weddings; Caroline James, Stephen Altschul"
