How to find RsaI sites in a sequence

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

Frequently asked questions

What sequence does RsaI cut?

RsaI recognizes GTAC (written 5' to 3') and cuts the top strand at GT^AC.

Does RsaI leave sticky or blunt ends?

Blunt ends, with no overhang.

How often does RsaI cut?

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