Design Notes

The design included literature reading of examples to block the translation of proteins in bacteria, and particularly to those in which the target sequences were phages’ essential genes. The 5’ of the transcript should be blocked.
The secondary structures' free energies were all optimized (The less negative, the better) by recorring windows of different sizes within the target regions using the RNA folding server. The asRBSs are not blocked.
