Best answer

The correct choice is (b) False

Explanation: The lower the E value, the more significant the alignment between a pair of matching sequences. The E value of an alignment score is the probability that an alignment score as good as the one found would be observed between two random or unrelated sequences in a search of a database of the same size.

In protein/domain analysis, each protein in the predicted proteome is again used as a query of a curated protein sequence database such as ____ in order to locate similar domains and sequences. To find orthologs, very low E value scores (E<10<20) for the alignment score and an alignment that includes 60–80% of the query sequence are generally required in order to avoid matches to paralogs.
