Design notes
For this genetic construction, we followed these summarized steps in the following image:
1) Transformation of DH5-alpha with the Biobrick - Strong RBS + merA (mercuric ion reductase)+ terminator (BBa_ B0015) - BBa_K1355000 and with the Essential Biobrick - Regulation and transport of mercury - BBa_K1355001 that contains a bidiretional promotor regulated by the MerR protein.
2) Extraction and quantification of plasmid DNA of the BBa_K1355000 and BBa_K1355001;
2) Verifying the electrophoretic profile of the extracted plasmid DNA;
Figure 1: Eletrophoretic profile of the BBa_K1355001 and of BBa_K1355000 plasmid DNA.
3) Restriction enzyme digestion of the BBa_K1355001 with SpeI and EcoRI and of BBa_K1355000 with EcoRI and XbaI aiming to isolate the biobrick fragment and linearize the vector, respectively;
4) Checking the electrophoretic profile of digested samples;

5) Purification from agarose gel of the fragment (Biobrick BBa_K1355001) and the linearized vector (BBa_K1355000);
4) Checking the electrophoretic profile of purified samples;

6) Ligation of the linearized vector with fragment using T4 DNA ligase;
7) Transformation of the ligation in DH5-alpha;

8) Extraction of plasmid DNA with our bioremediator constrution from DH5-alpha transformed;
9) Check the electrophoretic profile to see results of samples linked;

10) Restriction enzyme digestion of BBa_K1355001 + BBa_K1355000 (BBa_K1355004) with EcoRI + PstI aiming to analyze the fragment size to be isolated;
11) Checking the electrophoretic profile of the digested sample to obtain results showing that the isolated fragment is the junction of BBa_K1355001 + BBa_K1355000 in pBSK;
