      The output from a “BLAST search” is a series of sequence alignments. EXAMPLE OF A BLAST SEARCH. Suppose you have the sequence of a human protein and want to know if there is a homologous protein in the fruit fly Drosophila melanogaster. The amino acid sequence of the human protein will be the “ query ” for the BLAST search. The . BLAST ...

      An extremely powerful bioinformatics tool is BLAST, which stands for Basic Local Alignment Search Tool. Using BLAST, you can input a gene sequence of interest and search entire genomic libraries for identical or similar sequences in a matter of seconds. In this laboratory investigation, you will use BLAST to compare several genes, and then use ...

      BLAST (Basic Local Alignment Search Tool) was developed in 1989 at the National Center for Biotechnology Information (NCBI) at the National Institutes of Health (NIH). BLAST uses statistical methods to compare a DNA or protein input sequence (a.k.a. “query sequence”) to a database of sequences (“subject sequences”) and return those ...

      Students transcribe and translate a given sequence of DNA and perform a BLAST search against a database of known proteins to determine which protein their sequence encodes. The goal is to show students that genes encode proteins, which in turn can cause disease if mutated or function improperly. Background
