Mather All organisms are controlled by their genes, which are coded by DNA, which is copied to RNA, which creates proteinswhich are sequences of amino acids. DNA resides in the nucleus. Using yeastKornberg identified the role of RNA polymerase II and other proteins in transcribing DNA, and he created three-dimensional images of the protein cluster using X-ray crystallography.

Kornberg and his research group have made several fundamental discoveries concerning the mechanisms and regulation of eukaryotic transcription.

While a graduate student working with Harden McConnell at Stanford in the late s, he discovered the "flip-flop" and lateral diffusion of phospholipids in bilayer membranes. With Yahli Lorch, Kornberg showed that a nucleosome on a promoter prevents the initiation of transcription, leading to the recognition of a functional role for the nucleosome, which serves as a general gene repressor.

Through the work of Kornberg and others, it has become clear that these protein components are remarkably conserved across the full spectrum of eukaryotes, from yeast to human cells.

Using this system, Kornberg made the major discovery that transmission of gene regulatory signals to the RNA polymerase machinery is accomplished by an additional protein complex that they dubbed Mediator. The discovery of Mediator is therefore a true milestone in the understanding of the transcription process.

Initially, Kornberg took advantage of expertise with lipid membranes gained from his graduate studies to devise a technique for the formation of two-dimensional protein crystals on lipid bilayers. Eventually, Kornberg was able to use X-ray crystallography to solve the 3-dimensional structure of RNA polymerase at atomic resolution.

According to the Nobel Prize committee, "the truly revolutionary aspect of the picture Kornberg has created is that it captures the process of transcription in full flow.

Kornberg has also been a director for the following companies: Awards and honors[ edit ].Arthur Kornberg Severo Ochoa de Albornoz (Spanish: [seˈβeɾo oˈtʃoa ðe alβorˈnoθ] ; 24 September – 1 November ) was a Spanish -American physician and biochemist, and joint winner of the Nobel Prize in Physiology or Medicine with Arthur Kornberg.
