University of Alberta researchers have found an answer to a fundamental question in genomic biology that has eluded scientists since the discovery of DNA: Within the nucleus of our cells, is the complex package of DNA and proteins called chromatin a solid or a liquid?
Cell, the research team, led by Department of Oncology professor Michael Hendzel and collaborator Jeffrey Hansen from Colorado State University, found that chromatin is neither a solid nor a liquid, but something more like a gel.
Previously, fields such as biochemistry operated under the assumption that chromatin and other elements of the nucleus operated in a liquid state, Hendzel said. This new understanding of the physical properties of chromatin challenges that idea, and could lead to a more accurate understanding of how the genome is encoded and decoded.
