* E. coli bacteria: This served as the host organism.
* Plasmid: This was a small, circular piece of DNA that they isolated from E. coli. They used this plasmid as a vector to carry the desired gene.
* Antibiotic resistance gene: This was a gene from another organism (likely another bacterium) that provided resistance to a specific antibiotic. This gene was inserted into the plasmid.
Here's the basic breakdown of the experiment:
1. Isolation: They isolated the plasmid DNA from E. coli and the antibiotic resistance gene from another organism.
2. Restriction Enzyme Digestion: They used restriction enzymes to cut both the plasmid and the antibiotic resistance gene at specific locations.
3. Ligation: They then joined the cut ends of the plasmid and the antibiotic resistance gene using DNA ligase, creating a recombinant plasmid.
4. Transformation: They introduced the recombinant plasmid into E. coli.
5. Selection: They used antibiotics to select for E. coli that had successfully taken up the recombinant plasmid.
This experiment demonstrated the feasibility of gene cloning, a fundamental technique in modern biotechnology.
