How to search a sequence with mismatches

Choose DNA or protein under Sequence type, then paste the sequence, as plain text or FASTA.
Type the query and the number of mismatches allowed.
Every place that matches with that many mismatches or fewer is listed with its position, strand and the number of mismatches.

Frequently asked questions

Are gaps allowed?

No. Only substitutions count as mismatches; the match has the same length as the query.

Is my sequence uploaded?

No. Everything runs in your browser, so your sequences never leave your device.
