The sensitivity of BLAST searches may be enhanced in various ways. One possibility is to iteratively build a potent scoring matrix by running successive database searches. What is the name of the BLAST program used to do this? Generally, why is this a more sensitive approach? What might compromise search results?

(a) What is the advantage of a seeded method like BLAST compared to Needleman-Wunsch alignment? (b) Which flavor of BLAST is most sensitive for comparing your sequence to species that are NOT closely related? Explain in one sentence. (c) In Karlin-Altshul statistics, what are the four main assumptions? Describe a scenario where BLAST will be incapable of finding a high-quality match, even when one exists in the database. To get full credit, you must specify the word hit length utilized by BLAST in your scenario AND state the actual percent identity of your query to the best sequence in the database (which BLAST is unable to find).
