1. Fluorescence microscope results

Our plasmid design contains a RFP and GFP. Fluorescence microscope pictures Figure 1 shows that GFP is expressed.

(Figure 1 Those bacteria who express GFP is seen under the fluorescence microscope activated by 488nm light.The picture shows the expression of the GFP. )

2.Flow cytometry results

Figure2-a

Figure2-b

Flow cytometry results of GFP expression in experiment group Figure2-a and control group Figure2-b.The average GFP fluorescence strength of control group is 432 unit and of experiment group is 251 unit. Therefore, the terminator efficiency is 251/432=0.58

3.Agreement with theoretical prediction

(Figure 3 According to our experiment measured terminator efficiencies and our software predicted dscores, we create fit curve to relate all the data . To correspond to the figure 3, we choose linear fit curve to link all the data. There are 5 valuable points of terminator efficiencies. The sequences are listed below. In the experiment, we transform 9 terminators to plasmid mutant-psb1a3-GF and only get 5 reliably terminators’ data. The points appeared on the figure are terminators whose number is 1,4,6,7,8 )

(Figure 4 Here listed the sequences of terminator whose efficiencies are measured in the lab.)
