Blast

Blast is an explosion or the destructive wave of highly compressed air spreading outward from it.

In bioinformatics, BLAST is shorter form for Basic Local Alignment Search Tool, which consists of a set of algorithms. BLAST is used to compare biological sequences like protein sequences or nucleotides. A comparison of individual sequence can be done with it against a database of sequences and information obtained in case there is matching of sequences. It can also be applied for aligning two sequences and examining the resemblance between two or more sequences.
