Why are there multiple results returned when you input a sequence into BLAT or BLAST? How do you know which is most relevant? Does that make the others irrelevant ?

Answer #1

BLAST = Basic Local Alignment Search Tool
It is a software tool used to search unknown sequences using sequence similarity/identity.

When a BLAST search is performed, several results are obtained.
These results represent multiple sequences from different organisms that exhibit sequence similarity with the query sequence.
If the query sequence is conserved, the number of results will be high.

Among the BLAST results, we have to choose the result which has maximum similarity/identity and sequence coverage.

It does not make other results irrelevant. It just shows that such sequences are also found in other organisms.
