BASIC LOCAL ALIGNMENT SEARCH TOOL

BLAST finds regions of similarity between biological sequences. The program
compares nucleotide or protein sequences to sequence databases and calculates
the statistical significance. Learn more
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 members of gene families.
