How to find HaeIII sites in a sequence

  1. Paste a DNA sequence or FASTA record into the box above. HaeIII is already entered under Only these enzymes.
  2. Tick Circular DNA for a plasmid, so a site that spans the end and the start is found.
  3. The map marks each HaeIII cut with its position. Copy or download the output below it.

Frequently asked questions

What sequence does HaeIII cut?

HaeIII recognizes GGCC (written 5' to 3') and cuts the top strand at GG^CC.

Does HaeIII leave sticky or blunt ends?

Blunt ends, with no overhang.

How often does HaeIII cut?

A site like GGCC turns up about once every 256 bp in random DNA. Real sequences vary, so check yours above.
