Bioinformatics
  • Interdisciplinary science that involves
    developing and applying information technology
    for analyzing biological data

Overview of Bioinformatics

BLAST
  • The BLAST programs (Basic Local Alignment Search
    Tools) are a set of sequence comparison
    algorithms that are used to search international
    sequence databases for regions of similarity
    between sequences

BLAST
Program  Description
blastp Compares an amino acid query sequence against a protein sequence database.
blastn Compares a nucleotide query sequence against a nucleotide sequence database.
blastx Compares a nucleotide query sequence translated in all reading frames against a protein sequence database. You could use this option to find potential translation products of an unknown nucleotide sequence.
