State
Sequence alignment arranges DNA, RNA, or protein sequences to identify shared regions; BLAST is software that searches a database for sequences matching a query.
Show
Entering one short DNA sequence into BLAST returns every location in a chosen genome with a closely matching sequence.
Watch for
A BLAST match shows sequence similarity at the searched region — it does not establish identical function.
