How to find AflII sites in a sequence

  1. Paste a DNA sequence or FASTA record into the box above. AflII 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 AflII cut with its position. Copy or download the output below it.

Frequently asked questions

What sequence does AflII cut?

AflII recognizes CTTAAG (written 5' to 3') and cuts the top strand at C^TTAAG.

Does AflII leave sticky or blunt ends?

Sticky ends: a 4-base 5' overhang (TTAA).

How often does AflII cut?

A site like CTTAAG turns up about once every 4,096 bp in random DNA. Real sequences vary, so check yours above.
