How to find a motif in DNA

Paste a DNA sequence, as plain text or FASTA.
Type the pattern, such as GAATTC or TATAWAW. IUPAC codes match any of their bases.
Every match is listed with its start, end and strand.

Frequently asked questions

Can I use a regular expression?

Yes. A pattern with characters such as [ ] ( ) * + or ? is used as a regular expression, for example GC[AT]{2,4}GC.

Is my sequence uploaded?

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