A small piece of DNA is extracted from a circular form of bacterial or yeast DNA called a plasmid. A scientist will extract this DNA through using specific restriction enzymes. Then, a scientist will insert the human gene for insulin into the gap left by the extracted DNA. This plasmid is now considered a genetically modified entity.
Liposomes and polymers can be used as vectors to deliver DNA into cultured animal cells. Positively charged liposomes bind with DNA, while polymers can designed that interact with DNA. [36] They form lipoplexes and polyplexes respectively, which are then up-taken by the cells. Other techniques include using electroporation and biolistics. [39]
Electroporation of DNA, RNA, or ribonucleocomplexes is a common technique, though it can result in harmful effects on the target cells. [79] Chemical transfection techniques utilizing lipids and peptides have also been used to introduce sgRNAs in complex with Cas9 into cells. [80] [81] Nanoparticle-based delivery has also been used for ...

With the discovery of various types of immune-related disorders, there is a need for diversification in prevention and treatment. Developments in the field of gene therapy are being studied to be included in the scope of this treatment, but of course more research is needed to increase the positive results and minimize the negative effects of gene therapy applications. [27]
The extreme sensitivity of the technique can be a double-edged sword since even the slightest DNA contamination can lead to undesirable results. [48] A simple method for elimination of false positive results is to include anchors, or tags, to the 5' region of a gene specific primer. [49]
Modern biology and biochemistry make intensive use of these techniques in recombinant DNA technology. Recombinant DNA is a man-made DNA sequence that has been assembled from other DNA sequences. They can be transformed into organisms in the form of plasmids or in the appropriate format, by using a viral vector. [159]
