    - PCR amplification of fadD, fadL inserts

    - Purification of fadD, fadL PCR products

    - LB plate preparation with chloramphenicol (34ug/ml) for selection of pSB1C3 clones

    - DH5α competent cells are transformed with BBa_B0030 and BBa_R0040 separately by heat shock

    - 1st Extraction of BBa_B0030, BBa_R0040 by miniprep
    -> low product yield of BBa_R0040

    - Extraction of BBa_R0040, by miniprep

    Results: No band was observed for BBa_B0030 after digestion
    -> Gel photo showed the extracted BBa_B0030 DNA was contaminated with RNA leading to overestimation of BBa_B0030 concentration for restriction digestion

    - Purification was performed on the digested fadL and fadD inserts and BBa_R0040 products

    - Ligation of digested fadD insert into BBa_B0030 vector was performed

    - Restriction digestion of BBa_B0030 was performed with SpeI and PstI

    - Digested BBa_B0030 was purified with PCR purification kit

    - fadL insert was ligated into BBa_R0040 vector
