Why is Blast faster than Fasta?
Why is Blast faster than Fasta? This step is one of the main differences between BLAST and FASTA. FASTA cares about all of the common words in the database and query sequences that are listed in step 2; however, BLAST only cares about the high-scoring words. This allows the program to rapidly compare the high-scoring […]
