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 be used to infer functional and evolutionary relationships between sequences as well as help identify ...

PSI-BLAST allows the user to build a PSSM (position-specific scoring matrix) using the results of the first BlastP run. PHI-BLAST performs the search but limits alignments to those that match a pattern in the query. DELTA-BLAST constructs a PSSM using the results of a Conserved Domain Database search and searches a sequence database.
BLAST (biotechnology) 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.
Aug 6, 2024 · The Basic Local Alignment Search Tool (BLAST) finds regions of similarity between sequences. The program compares nucleotide or protein sequences and calculates the statistical significance of matches. BLAST can be used to infer functional and evolutionary relationships between sequences as well as help identify members of gene families.

BLAST is an acronym for Basic Local Alignment Search Tool and refers to a suite of programs used to generate alignments between a nucleotide or protein sequence, referred to as a “query” and nucleotide or protein sequences within a database, referred to as “subject” sequences. The original BLAST program used a protein “query ...
Aug 3, 2023 · BLAST is a powerful tool for analyzing biological sequence data. Since the initial release of BLAST in 1990, it has undergone continuous updates to improve its speed and accuracy. BLAST is now considered a crucial and widely used tool in the field of bioinformatics.
