DNA Part of an RNA·DNA-DNA triple helix

It was proved by Kunkler et al. that this sequence creates a triple helix with the RNA part (BBa_K3657022) in vitro.

More information available here: LINK

Usage and Biology

Triple helices are one of the alternative structures formed by nucleic acids. In addition to the Watson-Crick interactions between base pairs, Hoogsteen interactions are crucial for the formation of the triple helix. The binding is sequence specific.

Part Design

You can generate analogical parts yourself as following:

  1. Generate a random DNA sequence containing adenine, cytosine and guanine. You sequence should be longer than 19 base pairs and preferably should not contain thymine.
  2. Use the following script to generate RNA: LINK. Corresponding bases in the script are the pairs that create strongest bonds according to Kunkler et al.
