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.
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...
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.
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.
BLAST can rapidly align and compare a query DNA sequence with a database of sequences, which makes it a critical tool in ongoing genomic research.
The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between protein or nucleotide sequences. The program compares nucleotide or protein sequences to sequence in a database and calculates the statistical significance of the matches.
Mar 17, 2014 · BLAST for beginners introduces students to blastn, a commonly used tool for comparing nucleotide sequences (DNA and RNA). This popular tutorial shows how to do a blast search with a nucleotide sequence, highlights information in the search results, and shows how to interpret the E value and alignment scores.
Jun 23, 2008 · Basic Local Alignment Search Tool (BLAST) is probably the most popular similarity search tool. The National Center for Biotechnology Information (NCBI) first introduced BLAST in 1989. The NCBI has continued to maintain and update BLAST since the first version.
BLAST Highlights. NCBI has recently designed the BLAST interface to improve usability. New features include: A list of search results performed within the past 36 hours. Search strategies that can be saved to MyNCBI. Reorganized home-page links to BLAST forms.
