In the past 50 years, the field of medicine has experienced tremendous advancements ranging from the discovery of new diagnostic techniques, treatment therapies and life-saving medical devices. In practice, advances in the medical technology have influenced mankind in the universe by providing solutions to health conditions, cure for diseases and production of food products. Despite the achievement of many breakthroughs in the medical biotechnology in the past 50 years, it is apparent that the discovery of Recombinant DNA in 1973 by Herbert Boyer and his colleague Stanley N. Cohen at Stanford University Medical School is the single greatest breakthrough in medical biotechnology. Justification for recombinant DNA technology being regarded as the single greatest breakthrough in medical biotechnology is provided by its impact in the field of medicine, industrial process and agricultural production. Foremost, the use of the recombinant technology has led to the development of new vaccines, therapeutic remedies to various conditions including gene therapy for genetic disorders, development of modern diagnostic procedures, and advances in food production through the use of genetically modified organisms.

Discovery of Recombinant DNA: The Single Greatest Breakthrough in Medical Biotechnology in the Past 50 Years
In the past 50 years, the field of medicine has experienced tremendous advancements ranging from the discovery of new diagnostic techniques, treatment therapies and life-saving medical devices. In practice, advances in the medical technology have influenced mankind in the universe by providing solutions to health conditions, cure for diseases and production of food products. Despite the achievement of many breakthroughs in the medical biotechnology in the past 50 years, it is apparent that the discovery of Recombinant DNA in 1973 by Herbert Boyer and his colleague Stanley N. Cohen at Stanford University Medical School is the single greatest breakthrough in medical biotechnology.
Herbert Boyer and his colleague used molecular cloning to create recombinant DNA from the bacterial genomes; DNA and plasmid (Russell & Sambrook, 2001). They transformed E. Coli by inserting foreign DNA segments into the bacterial DNA strand to create a new genome that could express the bacterial genes contained in its original DNA, as well as genes in the foreign DNA insert from the donor organism. As a result, the transformed bacteria commonly referred to as the recombinant cell was able to express replicate the foreign DNA insert through bacterial division to produce more transformants. In addition, the recombinant bacteria produced respective proteins encoded by the genes in the foreign DNA insert.
In the experiment which led to the creation of the recombinant DNA, inventors of the technology molecular cloning techniques, especially DNA digestion by restriction enzymes. It involved E. Coli as the host, plasmid as the vector and the foreign DNA segment from the desired organism. The procedure involved obtaining the plasmid from bacteria, the DNA from the donor organism, the host cells, and restriction enzymes. Restriction enzymes were used to create DNA fragments from the donor DNA molecule. This DNA fragment (insert) was inserted into the plasmid strand using restriction enzymes to slice the plasmid for the insertion of the foreign DNA insert.
