BLAST

BLAST stands for

PSI BLAST is better than BLAST

why PSI BLAST is better than BLAST alone

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

Look at this flow chart . This refers to

• BLSATp

• BLASTn

• BLASTt

• PSIBLAST
