Question

Emotif uses which databases for alignment of sequences?

(a) BLOCKS and PRINTS databases

(b) PROSITE

(c) BLOCKS

(d) PRINTS

I have been asked this question by my college director while I was bunking the class.

I want to ask this question from Motif and Domain Databases Using Regular Expressions in chapter Sequence Alignment of Bioinformatics

Answer 1

Correct choice is (a) BLOCKS and PRINTS databases

The explanation is: Emotif is a motif database that uses multiple sequence alignments from both the BLOCKS and PRINTS databases with an alignment collection much larger than PROSITE. It identifies patterns by allowing fuzzy matching of regular expressions. Therefore, it produces fewer false negatives than PROSITE.
