*: Depending on the type of your query sequence, two different kinds of the BLAST program can be run:
- BLASTP, Protein Query Searching a Protein Database
Each database sequence is compared to each query in a separate
protein-protein pairwise comparison.- BLASTX, Nucleotide Query Searching a Protein Database
Each query is translated, and each of the six products is compared to
each database sequence in a separate protein-protein pairwise comparison.
