- The given sequence is compared with sequences in the database using substitution matrices that specify scores to either 'reward' a match or 'penalize' a mismatch.
- Top scoring matches are ranked according to set criteria that serve to distinguish between a similarity due to ancestral relationship or due to random chance.
- True matches are further examined thoroughly with other details accessible through Entrez and other tools available at NCBI.
