How to find NheI sites in a sequence

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

Frequently asked questions

What sequence does NheI cut?

NheI recognizes GCTAGC (written 5' to 3') and cuts the top strand at G^CTAGC.

Does NheI leave sticky or blunt ends?

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

Which enzymes leave ends compatible with NheI?

AvrII, SpeI and XbaI. Their overhangs are the same, so the ends can be ligated to each other.

How often does NheI cut?

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