Webthe cognate (trigger) RNA. Toehold switches are composed of the so-called toehold sequence at the 5’ of the switch RNA, followed by a hairpin structure that sequesters the RBS and the start codon, and ending with the mRNA sequence of the reporter gene. The toehold switch provides the binding site for the initial hybridization with the trigger ... Webhairpin toehold and loop length necessary for stable hybridization. Imposing this design constraint to promote hairpin polymerization did not prevent us from retaining hairpin metastability under the same stringent hybridization conditions. To partially counteract the necessary increase in hairpin size, we switched from DNA to RNA brushed brass kitchen sink and tap
