The advantage of the enzyme was that it cut DNA into pieces with overlapping, single-stranded ends. This opened up a means to rejoin DNA fragments in a similar way to a lap-joint in wood joinery. By they had succeeded in this endeavour using both Boyer's enzyme and a bacterial plasmid, pSC, isolated by Cohen. Their breakthrough paved the way to the widespread adoption of genetic engineering in both academic and industrial settings. In subsequent years Boyer continued to make improvements to recombinant DNA technology and was involved in its first commercialisation.
Boyer is not only associated with the development of the first method for cloning DNA, but also with the founding of Genentech, the first dedicated biotechnology company. This he did with the venture capitalist Robert Swanson in Serving as Genentech's vice president between and , Boyer led the company's efforts in demonstrating how bacteria could be genetically modified for the mass production of human proteins, such as insulin and growth hormones, for therapy.
Such work helped fuel the birth of the modern biotechnology industry. Boyer has received numerous awards for his achievements. Temporary moratorium called for on genetic engineering until measures taken to deal with potential biohazards. Whilst you are here We are working hard every day to educate and encourage young people across the world to discover a love of science and to become involved by creating accessible, well-researched material that helps educate and inform students and the public about life-saving medicines and the scientists who make those medicines possible.
But we can't do it on our own, we need support from readers and users of WhatIsBiotechnology. In , near the end of his high school days, Boyer found two heroes: Francis Crick and James Watson, the scientists who had just discovered DNA's double helix structure. Cutting and Cloning Boyer arrived in San Francisco in -- at the height of its Sixties counterculture.
An active civil rights and anti-war protester, Boyer was now a biologist and new assistant professor at the University of California. In late-night lab sessions, he found a way to cut certain strings of DNA into "cohesive" segments, with the aid of an isolated enzyme. Boyer was able to cut the code for a specific protein and attach it to other DNA.
This became known as recombinant DNA technology. My laboratory continued to explore the improvement of this technology with the development of plasmids with more efficient and flexible utility.
We engaged in a project with Drs. Riggs and K. With the development of techniques for determining the sequence of nucleotides in a DNA molecule, in vitro recombination, and the ability to chemically synthesize DNA a new horizon appeared. At this time I was approached by a young venture capitalist, Robert Swanson, inquiring about the feasibility of starting a company based upon the above-mentioned technologies.
After several discussions we obtained funding to demonstrate that it was possible, by using chemically synthesized DNA to direct bacteria to produce a human protein. With this proof of concept we proceeded to form the first biotechnology, Genentech, Inc.
In he accepted an appointment at UCSF, which was becoming a center of excellence in the several disciplines that contributed to the emerging field of biotechnology. They became frustrated, however, when the enzyme cut the DNA in five places instead of one, as desired. November found both Boyer and Cohen in Hawaii giving papers at a U. While Boyer was describing his data showing the nature of the DNA ends generated by EcoRI cleavage, Cohen was reporting on a procedure recently discovered in his laboratory that enabled bacteria to take up plasmid DNA and produce offspring that contained self-replicating plasmids identical to the original implant—clones.
Over sandwiches late one night at the conference, the two men laid plans for a collaborative project to discover what genes are present on plasmids and how they are arranged. After completing his medical education he began a full-time career in medical research and teaching at the Albert Einstein College of Medicine in New York. There he worked on the complex mechanisms that control gene expression in the bacterial virus lambda.
In he accepted an appointment at the Stanford University School of Medicine. The collaboration between Boyer and Cohen was very close.
