Science 360 (NSF, March 24) -- Proteins play a large role in DNA regulation, but a new study finds that DNA molecules directly interact with one another in a way that’s dependent on the sequence of the DNA and epigenetic factors. This could have implications for how DNA is organized in the cell and even how genes are regulated in different cell types, according to postdoctoral researcher Jejoong Yoo, and Aleksei Aksimentiev, an associate professor of physics at Illinois.
