Which of the following statements is not correct with respect to BLAST algorithm?

• We should mask low complexity regions to speedup BLAST

• We should build indices for seed words in advance to speedup BLAST

• We should use fixed seed words inorder to speedup BLAST

• We should use shorter seed words inorder to speedup BLAST

Which of the following statements is not correct with respect to BLAST algorithm?

• We should mask low complexity regions to speedup BLAST

• We should use dynamic programming at the first stage to speedup BLAST

• We should build indices for seed words in advance to speedup BLAST

• We should use longer seed words inorder to speedup BLAST

What is the impact of increasing word size (W) on BLAST algorithm

• specificity increases

• sensitivity increases

• speed increases

• speed decreases

• sensitivity decreases

Listen to this tutorial about BLAST and then answer if BLAST searches

• only DNA sequences

• only RNA sequences

• Only Protein sequences

• all of the above
