How to find SacII sites in a sequence

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

Frequently asked questions

What sequence does SacII cut?

SacII recognizes CCGCGG (written 5' to 3') and cuts the top strand at CCGC^GG.

Does SacII leave sticky or blunt ends?

Sticky ends: a 2-base 3' overhang (GC).

How often does SacII cut?

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