blast

 [blast]
1. an immature stage in cellular development before appearance of the definitive characteristics of the cell; used also as a word termination, as in ameloblast and trophoblast.
blast cell.
2. the wave of air pressure produced by the detonation of high-explosive bombs or shells or by other explosions; it causes pulmonary damage and hemorrhage (lung blast, blast chest), laceration of other thoracic and abdominal viscera, ruptured eardrums, and effects in the central nervous system.

BLAST

Basic Local Alignment Search Tool. A nucleic acid- and protein-sequence comparison algorithm which is used to find matches in gene sequences and to search sequence databases for optimal local alignments to a query sequence.

BLAST uses a heuristic algorithm, seeking local alignments and creating a matrix of similarity scores for all possible pairs of residues, defining high-scoring segments, statistically evaluating the significance of the results and detecting relationships among sequences which share only isolated regions of similarity.

BLAST (Basic Local Alignment Search Tool)

a sequence comparison algorithm used to search DNA or PROTEIN databases. For example, BLASTN is used for homology searching to compare nucleotide sequences.

The query sequence is entered and compared with a nucleotide sequence database.
