  <p>The  aim of this study is to construct a fluorescent digital&nbsp;display device of  genetic circuits with synthetic logic gates, which can both display and switch  numbers. Similar to electronic circuits, logic regulation operation in cells  integrates the extracellular and intracellular signals. We assemble several  pairs of promoters and their activators (or repressors) into computing building  block of the circuit: <em>PBAD</em>-Arabinose, <em>PcI</em>-CI, and <em>PtetR</em>-TetR. As shown in  Figure 1, these computation units act as genetic logic gates perform AND, OR  and NOT gates function. In order to light up our digital numbers, we put Green  Fluorescent Protein (GFP) in the downstream expression, which is ubiquitous in  the field of biological signal protein. Considering that the common types of  GFP usually tend to be very stable and hard to &quot;quench&quot;, we choose  unstable GFP to make our device reusable and convert in a fast speed. This  unstable GFP is tagged with a C-terminal extension, which will be recognized  and degraded by tail-specific proteases, leading to a short half-life and fast  degradation of the protein.Degradation rate should be confined at a  suitable range, otherwise the device would either have no light or take a long  time to change numbers .</a><br />

  <p>Moreover, we intend to  develop a unique display device in such a way that each unit lights up one  after another. To meet the challenge, we set out to engineer a series of cells  with variable time-delayed expression characters under the inspiration of Feed  Forward Loops (FFLs) in transcription network. As shown in Figure 2, both X and  Y are transcriptional activators of coherent type 1 FFL with  &quot;AND-gate&quot; function. When signal Sx appears, X becomes  active and stimulates the downstream promoters, which are capable of inducing  the production of Y and Z. Due to the &quot;AND gate&quot; function, Z starts  to accumulate only when Y yields at a threshold. By controlling the Y  production and the activation threshold for the <em>Z</em> promoter, we can alter the duration of time-delay in the  expression of GFP. Lux system will still play an  important role based on our project last year. Promoter <em>luxpR</em> with various modifications in threshold will be created by  site-directed mutagenesis.</p>
