In human cells, scientists find DNA that looks like a twisted knot instead of a double helix - Los Angeles Times


Los Angeles Times
Laurence Hurley, a professor of medical chemistry at the University of Arizona who was not involved with the study, said the new paper is important for chemical biology and molecular therapeutics. He added that the new work lends credence to the idea ...

This is a research group within the Stanford Medical Informatics laboratory directed by Russ Altman, MD, PhD. We focus on the application of computational techniques to problems in molecular biology. We are particularly interested in (1) knowledge-based systems for supporting scientific computation (2) the representation and manipulation of structural uncertainty, (3) and the development of novel representations of structure that are useful for c
