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 identify unknown or new sequences, infer functional and evolutionary relationships between sequences, and identify members of gene families.
In Geneious Prime you can search external databases provided by NCBI, or search a custom database created from your own sequences. The result of a BLAST search will be an aligned set of potentially related sequences ranked according to similarity.
More information on BLAST can be found at http://en.wikipedia.org/wiki/BLAST.
