ABSTRACT
Â
DNA transformation is the process of inserting recombinant DNA into host cells via vector plasmid. The host cell that is often used is TOP-10 Escherichia coli. The transformation method is widely used to transfer plasmids containing genetic material. This study aimed to evaluate the results of plasmid transformation containing the merB gene in the Escherichia coli TOP-10 bacteria. This study initiated with identification of the microbiology of host cells to be used, namely Escherichia coli TOP-10. Escherichia coli TOP-10 host cells were made into competent cells by transforming plasmids containing merB gene into Escherichia coli TOP-10 host cells using the heat shock method. The transformation results were evaluated by observing at the growth of Escherichia coli TOP-10 colonies on agar LB media containing ampicillin antibiotics. Plasmids on Escherichia coli TOP-10 were isolated and analyzed by 1% agarose gel electrophoresis. The results showed that the transformation of plasmids containing merB in Escherichia coli TOP-10 bacteria was successfully carried out as indicated by the growth of Escherichia coli TOP-10 bacteria on LB media agar containing ampicillin and the visualization on agarose gel resulted that the plasmid which carried the merB gene could be transformed in to the E. coli TOP-10 bacteria cell.

ABSTRAK
Â
Transformasi DNA merupakan proses memasukkan DNA kedalam sel bakteri. Metode transformasi dipakai secara luas untuk mantransfer plasmid yang mengandung bahan genetika. Penelitian ini bertujuan untuk mengevaluasi hasil transformasi plasmid yang mengandung gen merB pada bakteri Escherichia coli TOP-10. Penelitian ini didahului dengan identifikasi secara mikrobiologi bakteri Escherichia coli TOP-10. Bakteri Escherichia coli TOP-10 dibuat menjadi sel kompeten yang digunakan sebagai inang. Selanjutnya dilakukan transformasi plasmid yang mengandung gen merB kedalam sel inang E. coli TOP-10 menggunakan metode heatshock. Hasil transformasi dievaluasi dengan melihat adanya koloni E. coli TOP-10 pada media LB agar yang mengandung antibiotik ampisilin. Plasmid pada E. coli TOP-10 diisolasi dan dianalisis dengan elektroforesis gel agarose 1%. Hasil penelitian menunjukkan bahwa transformasi plasmid yang mengandung gen merB pada bakteri Escherichia coli TOP-10 berhasil dilakukan, ditunjukkan dengan adanya pertumbuhan bakteri E. coli TOP-10 pada media LB agar yang mengangandung ampisilin dan hasil visualisasi pada agarose gel terlihat bahwa plasmid yang membawa gen merB dapat ditransformasikan ke dalam sel bakteri E. coli TOP-10.
