How to find BclI sites in a sequence

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

Frequently asked questions

What sequence does BclI cut?

BclI recognizes TGATCA (written 5' to 3') and cuts the top strand at T^GATCA.

Does BclI leave sticky or blunt ends?

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

Which enzymes leave ends compatible with BclI?

BamHI, BglII and Sau3AI. Their overhangs are the same, so the ends can be ligated to each other.

How often does BclI cut?

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