Scientists Discover New Type Of Human DNA That Defies The Science of Double Helix
Tech Times

For the first time, scientists have detected a DNA structure inside living human cells that looks more like a four-stranded knot than the elegant double helix we know from biology textbooks. Dr. Laurence Hurley, a BIO5 member and professor of medical chemistry at the UA who was not involved with the study, said the new paper is important for chemical biology and molecular therapeutics.
