Work

Major Academic Achievements:

Professor Kornberg discovered that the nucleosome, the basic unit of chromosomal DNA organization in the eukaryotic nucleus. He and Prof. Yahli Lorch showed that the nucleosome on a promoter prevents the initiation of DNA transcription, establishing the role of the nucleosome as a gene repressor, fundamental to the new field of epigenetics.Professor Kornberg solved the three-dimensional structure of RNA polymerase by, X-ray diffraction, both alone and in the form of an actively transcribing complex, containing gene DNA and product RNA. Professor Kornberg discovered the molecular basis for the regulation of transcription by gene activator and repressor proteins. His research laid a foundation for understanding the differentiation of stem cells and the mechanisms of human diseases and other important medical problems.
