Molecular DNA Repair

Authors: George Rajna

Using a piece of molecular "Velcro" to attach a light-emitting probe to a protein molecule, University of Wollongong (UOW) researchers have unlocked the mystery of how an important protein goes about repairing damaged DNA in bacteria, with implications for understanding how antibiotic resistance develops. [21] In new research, Hao Yan of Arizona State University and his colleagues describe an innovative DNA walker, capable of rapidly traversing a prepared track. [20] Just like any long polymer chain, DNA tends to form knots. Using technology that allows them to stretch DNA molecules and image the behavior of these knots, MIT researchers have discovered, for the first time, the factors that determine whether a knot moves along the strand or "jams" in place.
