Prof. Kornberg was awarded the Nobel Prize in Chemistry for his studies of the molecular basis of eukaryotic transcription. 

His pioneering research in the area of the structural biology of macromolecules has contributed to the understanding of how we view the structure and role of genetic expression, and has furthered our understanding of the basic process of life. He has conducted highly important research in the field of genetic expression of eukaryotic organisms (entities whose cells include a nucleus), research whose essential contribution has been the revelation of nucelosomes the elementary parts of chromosomes which participate in the control of genetic expression. Prof. Kornberg has also done basic, pioneering research on the subject of the structure and role of large enzymes which carry out the process of transcription of RNA the first step in genetic expression.
