Hi! I've blast a pair of sequences (wildtype vs mutant), doing it exactly as the tutorial shows, but in the "aligments" section there are some "aaaa" in the query sequence, this is: Query 1440 TGAACATGAGAATATTTTCAAAGTAGGCTCATTAGCATTaaaaaaaaTCAATGAATTACC 1499 Sbjct 1441 ............................................................ 1500 Could anyone please explain to me what are these "aaaaaaaa" meaning? I'm making ARMS-PCR primers

Thanks
