Question

FASTA doesn’t use bit scores.

(a) True

(b) False

This question was posed to me in exam.

My query is from FASTA in chapter Database Similarity Searching of Bioinformatics

Answer 1

Correct choice is (b) False

To explain I would say: FASTA uses E-values and bit scores as well. Estimation of the two parameters in FASTA is essentially the same as in BLAST. However, the FASTA output provides one more statistical parameter, the Z-score.
