Isolation of a plasmid from a bacterium
Herbert Boyer and Stanley Cohen created the first recombinant DNA organism using recombinant DNA technology, or gene splicing, which allows the manipulation of DNA. They showed that the gene for a frog ribosomal RNA could be transferred and expressed in bacterial cells. Boyer and Cohen removed plasmids, small rings of DNA located in a cell's cytoplasm, from a cell. Using restriction enzymes, they cut the DNA at precise positions and then recombined the DNA strands in their own way using DNA ligase enzyme. They then inserted the altered DNA into E. coli bacteria. The bacterial cells could be made to produce specific proteins using gene splicing. This technology was a major breakthrough for genetic engineering. Their experiments dramatically demonstrated the potential impact of DNA recombinant engineering on medicine and pharmacology, industry and agriculture.
Bacteria were first used to copy genes through a process called recombinant DNA technology. This involved inserting a gene of interest into a plasmid, which was then introduced into the bacterial cell. The bacteria could then replicate and transcribe the gene, allowing for the production of a specific protein encoded by the gene.
There are many methods, though one of the most common is the use of restriction endonucleases. These enzymes can be used to cut DNA fragments at specific locations. Cut DNA fragments will recombine into new orders, which are sealed using DNA ligase. A selection process must be used to locate the desired recombinant DNA, since it will be in a mixture of various undesired recombinations.
To draw a plasmid map, you first need the plasmid sequence. Then, you can use specialized software like SnapGene or Benchling to input the sequence and generate a visual representation of the plasmid with features like genes, promoters, restriction sites, and other elements. Plasmid maps are typically presented as circular diagrams.
Restriction enzymes take apart the DNA in a certain area and allow for a plasmid to be inserted within the gap that is created. Restriction enzyme use is basically the same for both the production of recombinant DNA and for transgenic organisms since an organism can synthesize the DNA that has been inserted into it once it has been placed within the organism. In the case of unicellular organisms the restriction enzyme is first introduced to break apart the DNA and then the plasmid is introduced to create the desired effect. Then the organism can express those genes through further processing of the newly introduced DNA and through mitosis (which is how unicellular organisms reproduce) it can give that gene to its offspring. In the case of multicellular organisms a restriction enzyme and accompanying plasmid must be presented when the organism is just a zygote. This process is how those glow-in-the-dark fish are created and provided that those fish can reproduce they'll also give their traits on to future generations just like single-celled organisms would.

The scientific field that uses recombinant DNA is called genetic engineering.
