I'm trying to understand the concept of BLAST value in the context of bioinformatics. Could you explain what it represents and how it's used in sequence alignment?

It represents the number of hits of comparable quality or score that might occur randomly.

For instance, an E-value of 10 indicates that, in a random database of the same size, up to 10 hits of similar quality could be expected purely by chance.

This threshold serves as a guide to filter out insignificant matches and focus on those that are biologically relevant.
