Design Notes

The gRNA architecture includes two DR separated by the spacer with 4 additional base pairs downstream. So the final structure is: repeat + spacer + 4 nucleotides + repeat. Adding the promoter and the terminator right before and after the gRNA, the final architecture would be: T7 promoter + repeat + spacer + 4 nucleotides + repeat + L2S2P21 terminator.


Source

The repeat sequence was extracted from the parts registry (BBa_K2927006), whereas the spacer one was designed with the constraint that it had to be complementary to the sequence of the chloramphenicol-resistance gene aiming to be detected. (as explained in its own part page: BBa_K3791001).

The promoter and the terminator were also taken from Parts registry: BBa_K1614000, BBa_K2675031.
