Question

Which of the following is not a benefit or a factual of FASTA over BLAST?

(a) FASTA scans smaller window sizes

(b) It gives more sensitive results

(c) It gives less sensitive results

(d) It gives results with a better coverage rate for homologs

This question was addressed to me in homework.

The above asked question is from Comparison of FASTA and BLAST in portion Database Similarity Searching of Bioinformatics

Answer 1

The correct option is (c) It gives less sensitive results

To explain I would say: By default, FASTA scans smaller window sizes. Thus, it gives more sensitive results than BLAST, with a better coverage rate for homologs. However, it is usually slower than BLAST.
