Design Notes

By using the lin-4 gene pre-mRNA primary transcript F59G1.6 sequence found on WormBank, we designed our toehold switch RNA sequence using NUPACK software and software code provided by Yan Zhang. In addition to gaining the toehold switch sequence, we also obtained a complementary RNA trigger sequence. By inputting the minimum free energy structures for each of the switch and trigger combinations, NUPACK showed the possible structure, allowing us to determine whether or not each switch and trigger would have a high probability of working. The minimum free energy shown below demonstrates the strength of repression for the switch RNA and the single-strandedness of the trigger RNA for the activated complex. A negative ∆GRBS-linker value is correlated to a lower switch dynamic range.
