Examples of valid sequences:
Gardner's bistable switches
pIKE105
pIKE107
pTAK117
pTAK130
pTAK131
pTAK132

Clicking on one of links above will automatically load the sequences of valid constructs composed of multiple parts. Alternatively you can paste a sequence of your choice in this window. Try for instance to paste the sequence generated using the Design section of the site.

If a sequence is valid, the validation engine will represent the sequence by a series of icons labeled with the part identification number like at the end of the design process. If the construct is invalid, then an error message is displayed.
