in Figure 7.11B. However, at present, the instrument cannot measure the
fl uorescence of the input and output signals with the same reporter protein.
Therefore, in order to measure the fl uorescence of input and output signals
with the same reporter protein in vivo, the synthetic genetic transistor in
Figure 7.11B is divided into two parts with the same reporter protein, as
shown in Figure 7.13A and B. The portion shown in Figure 7.13A can be used
to measure the concentration of input signal, while ...
