Design Notes

Our team used the RNA thermometer as a part of a killswitch. The sequence was implemented before an antitoxin (ccdB) to regulate its translation based on temperature. It is possible to implement a part of the sequence of the gene that will be translated within the sequence that forms secondary hairpin structure. By doing this, leaky expression will be reduced. Because of the typical short sequence of this thermometer and the position of the startcodon, our team decided not to. The position of the startcodon can be found in the provided figure.
