RNA-based Delay, Biosynthetic AND gate: The plan

Due to the lack of information on siRNA, the enormous advantage and information of riboregulators and the previous work of Isaacs F. 2004, [http://openwetware.org/wiki/IGEM:UC_Berkeley/2006 Berkeley iGEM 2006], [http://openwetware.org/wiki/IGEM:Caltech/2007 Caltech iGEM 2007] and [http://parts.mit.edu/igem07/index.php/Peking Peking iGEM 2007], the riboregulator approach were selected. The construction of the plasmids is showed in figures 12 and 13.

Figure 12. Biosynthetic AND gate’s Plasmid 1. Upon induction with IPTG, the gene cI is transcribed but the Lock3c (biobrick) traps the RBS avoiding the expression of cI. cI will induce the expression of GFP in the plasmid 2.

Figure 13. Biosynthetic AND gate’s Plasmid 2. The addition of IPTG will induce the production of the Key3c (biobrick) which will allow the expression of cI and the induction of GFP production.
