Task 5. Information Systems

BLAST stands for Basic Local Alignment Search Tool.
BLAST is an online tool that is used by scientists to compare nucleotide or amino acid sequences in proteins and nucleic acid. Applications include the analysis of evolutionary relationships between species, determination of the role of a newly identified gene sequence or protein in a particular species, and identification of alternative species with similar genes or protein products.
Useful for demonstrating applications of gene technology, phylogenetic relationships between organisms and the role of point mutations in evolution (Year 11 and 12 Biology).
