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: <a href="https://github.com/igemsoftware2020/Heidelberg_2020/blob/main/CoNcoRDe/rnasupport/scripts/design_rna_triple_helix.py">link.</a>
   Corresponding bases in the script are the pairs that create strongest bonds according to Kunkler et al.
3. Attention! If you are adding other parts to your RNA, for example hairpins that interact with RNA binding proteins, makes sure that the added parts don't create a stable secondary structure with the triple helix part. Otherwise it may disturb the formation of the triple helix.</il>
