How to map primers on a sequence

Paste the DNA sequence.
Paste the primers one per line, each as a name followed by its sequence, or just the sequence.
Arrows mark where each primer binds: > on the top strand and < on the bottom.

Frequently asked questions

Do primers have to match exactly?

Yes. A primer is shown only where its whole sequence matches one of the strands.

Is my sequence uploaded?

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