Design Notes
We replaced the aptamer in the original riboswitch with an aptamer that would target our molecule of interest, atrazine. Because the atrazine aptamer that we found was meant to function as single-stranded DNA, we used its sequence in the coding strand of our plasmid so that the RNA transcript would have similar chemical properties to the original DNA design.
