Nov 28, 2023 · The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches.
In bioinformatics, BLAST ( basic local alignment search tool) [3] 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.
BLAST is a computer algorithm that is available for use online at the National Center for Biotechnology Information (NCBI) website, as well as many other sites. BLAST can rapidly align and...
Select the sequence database to run searches against. No BLAST database contains all the sequences at NCBI. BLAST databases are organized by informational content (nr, RefSeq, etc.) or by sequencing technique (WGS, EST, etc.). more...
Jun 23, 2008 · Sequence similarity searching is one of the more important bioinformatics activities and often provides the first evidence for the function of a newly sequenced gene or piece of sequence. Basic Local Alignment Search Tool (BLAST) is probably the most popular similarity search tool.
Aug 3, 2023 · BLAST stands for Basic Local Alignment Search Tool. It is a widely used bioinformatics program that was first introduced by Stephen Altschul et al. in 1990 and has since become one of the most popular tools for sequence similarity search.
Overview ¶. What is BLAST? The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches.
