Applications of Recombinant DNA

Recombinant DNA has a variety of important applications:

Insulin

Human insulin can be made by inserting the gene into a bacterial plasmid. The plasmid is then placed within bacterial cells.
As the bacteria cells divide, they produce insulin.
The insulin can be extracted and purified.
- This is a fast and efficient way to produce insulin. As the insulin is purified it is fast-acting when administered.

Factor VII

Individuals with haemophilia cannot produce factor VII.
Hamster cells can be genetically modified so they produce factor VII for treating haemophilia.
- This has the benefit of minimising the transmission of blood-borne diseases like HIV. This is because the factor comes from hamster cells rather than human blood.

Adenosine deaminase

Severe combined immunodeficiency (SCID) is a genetic condition that affects T lymphocytes. Sometimes other white blood cells are affected.
Affected individuals have difficulty fighting infections.
- It is treated by administering adenosine deaminase. Insect larvae can be genetically modified to produce adenosine deaminase.
