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.

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.
