BRAIDS 2

Caption

This illustration based on computational models by Rice University scientists shows coiled coil interactions with DNA. Coiled coils are not just passive actors, but have charge patterns that match up with the DNA, where an imposed twist on the coils leads to a bending of the DNA. Rice researchers believe this appears to be the starting point for the DNA extrusion process. The cohesin protein complex and its charged patterns are shown in gray and blue, respectively. DNA is shown in red.
